Notice the following diagram ! 42° X The measure of < x is 142⁰ - degrees.
1. Notice the following diagram ! 42° X The measure of < x is 142⁰ - degrees.
Jawaban:
80°
Penjelasan dengan langkah-langkah:
x = 42° + (180° - 142°)
x = 42° + 38°
x = 80°

3. What is the measure of angle x?
Jawaban:
102
Penjelasan dengan langkah-langkah:
x dalam segitiga itu cara hitungnya=180-(58+44)
=180-102
×segitiga=78
x=180-78
×=102

6. In a test to measure the depth of the sea bed, sound pulses took 0.40s to travel from the surface to the sea bed and back. Given that the speed of sound in the sea water is 1350m/s, calculate the depth of the sea bed below the surface.
Jawaban:
Echo sounding
High frequency sound waves can be used to detect objects in deep water and to measure water depth.
The time between a pulse of sound being transmitted and detected and the speed of sound in water can be used to calculate the distance of the reflecting surface or object.
The pcess is very similar to ultrasound imaging.
For deep water, 50 kHz is the preferred frequency of the ultrasound.
This is because water absorbs sound waves at a slower rate than for lower frequencies and so the signal can travel farther before becoming too weak to use.
This technique is applied in sonar systems used to measure the depth of the seabed and to find shipwrecks, submarines and shoals of fish.
SONAR stands for SOund Navigation And Ranging.
Bats and dolphins use a similar method, called echolocation, to detect their surroundings and to find food.
Example
A sonar system on a boat sends an ultrasound pulse towards the seabed.
The pulse is reflected, and it is detected 0.1 s later by the system.
Calculate the depth of water if the speed of sound in water is 1,480 m/s.
Answer
distance = speed × time
speed = 1,480 m/s
time for ultrasound to travel to seabed and back again = 0.1 s
time for ultrasound to travel to seabed = 0.1 s ÷ 2 = 0.05 s
distance to seabed = 1,480 × 0.05 = 74 m
The depth of water is 74 m
aim so sorry so wrong

10. Given measure of an angle is 2/3 of it's complimentary angle. The measure of that angle is
Let [tex]\alpha[/tex] be an angle so that [tex]\beta[/tex] is its complementary angle.
We know that:
[tex]\alpha + \beta = 90^o[/tex]
Plugging in [tex]\alpha = \frac{2}{3} \beta[/tex] we get:
[tex]\frac{2}{3} \beta + \beta = 90^o \\ \frac{5}{3}\beta = 90^o \\ \beta = 54^o[/tex]
So our final answer is:
[tex]\alpha = \frac{2}{3}\beta = \frac{2}{3}(54^o) = 36^o[/tex]

13. work the value of XandY,measure in centimetres
2x+3 = 19 (karena panjang atas dan bawah sama)
2x= 19-3
2x= 16
x = 16/2
x = 8
4y-6 = 22 (karna lebar bawah dan atas sama)
4y = 22+6
4y = 28
y = 28/7
y = 4
so, the value of x is 8 and the value of y is 4.

19. If the angles of a triangle are inthe ratio 1:3:5, then how many degrees are in the measure of the smalest angle?
Jawaban:
22.5 degrees
Penjelasan:
one triangle has total of 360 degrees
so :
one plus three plus five equals eight
small angle of triangle has a ratio 1 of 8 (1/8)
1/8 . 180 = 22.5 degrees
