Answer:
Step-by-step explanation:
<u>Sum of interior angles of any triangle is 180°:</u>
- 52° + 43° + x = 180°
- 95° + x = 180°
- x = 180° - 95°
- x = 85°
Answer:
a) 24
b) 10
c) 12/13
d) 5/13
e) 12/5
Step-by-step explanation:
a) We can see that the leg opposite <C is AB, and we are given AB = 24
b) We can see the leg adjacent to <C is AC, and we are given that AC = 10
c) The trig function sine is equal to

The opposite, AB, is 24, and the hypotenuse, BC, is 26. We can plug those numbers in:

d)The trig function cosine is equal to

The adjacent, AC, is 10, and the hypotenuse, BC, is 26. We can plug those numbers in:

d)The trig function tangent is equal to

The opposite, AB, is 24, and the adjacent, AC, is 10. We can plug those numbers in:

<u>Answer:</u>
Angle A = 39°
<u>Step-by-step explanation:</u>
We are given that there is a triangle ABC where a = 9, c = 5 and angle B = 120° and we are to find the measure of angle A.
But first we need to find the side b using the law of cosine:



Now finding angle A using law of cosine:




Therefore, the measure of angle A = 39°.
Answer:
x=1
y=-4
Step-by-step explanation:
- find x by making y to 0
- sub x into equation
- find y
Answer:
The first number lets say is x
the second is y so
y=1/2x+8
x+1/2x+8=58
1 1/2x=50
x= 33 1/3
