Answer:
Step-by-step explanation:
10.
- x + 57 = 116
- x = 116 - 57
- x = 59
11.
- y = 180 - 112 = 68
- x= 180 - 2*68 = 44
12.
- 4x + 10 = 180 - 2*40
- 4x + 10 = 100
- 4x = 90
- x = 90/4
- x = 22.5

Answer:
A
Step-by-step explanation:
An exponential function has the form
y = a
Use the given solutions to find a and b
Using (0, 3 ) , then
3 = a
[ = 1 ] , so
a = 3
y = 3
Using (1, 12 ) , then
12 = 3
= 3b ( divide both sides by 3 )
4 = b , then
h(x) = 3
→ A
Answer:
Part A:
given that cos β = 3/5
that means the base line is 3 and the hypotenuse is 5
Note that, The base line 3 is adjacent to β and opposite to α.
Sin α = opposite / adjacent
sin α = 3 /5
Part B:
α and β are complementary angles
Hey!!
here is your answer >>>
As we have learnt, the sum of angles A and B is exterior angle ,
so,
angle B would be
( 52 + x ) = 110
x = 110 - 52
x = 58!.
angle B is 58°
Sum of all angles in a trinagle is 180!.
angle C would be ,
52 + 58 + c = 180
110 + c = 180
c = 70
angles C is 70° !.
Hope my answer helps!
