Mathematics
1 answer:
Greeley [361]2 years ago
8 0

Answer:

a = 54

Step-by-step explanation:

In geometry, the angles in a triangle add up to 180.

The unmarked angle at the top of the triangle = 180 - (a+10+44)

Or you could say that same angle = 180 - 2a because it is supplementary to the exterior angle... so

2a = a + 10 + 44

2a-a = 54

a = 54

Let h(x)=2x+5, g(x)=8−3x. What is the value of h(g(1.5))?
Anon25 [30]

So your equation is a composite function. It means to plug 1.5 as x into g(x), then the answer you get for that, plug into h(x).

So.

g(1.5)=8-3(1.5)

=8-4.5

=3.5

Then.

H(3.5)=2x+5

=2(3.5)+5

=7+5=12

Your final answer is 12.
