Answer:

30 degrees.

Step-by-step explanation:

A triangle has 180 degrees. The two base angles are 75 degrees each. The third angle is x

75 + 75 + x = 180 Combine like terms on the left

150 + x = 180 Subtract 150 from both sides.

-150 -150

x = 30

The third angle is 30 degrees.

H(x) = 3x + 3<br> g(x)=-4x+1<br> Find (h+ g)(10)

Ratling [72]

Answer:

(h + g)(10) = -6

Step-by-step explanation:

Step 1: Define

h(x) = 3x + 3

g(x) = -4x + 1

Step 2: Find (h + g)(x)

(h + g)(x) = 3x + 3 + -4x + 1

(h + g)(x) = -x + 4

Step 3: Substitute and Evaluate

(h + g)(10) = -10 + 4

(h + g)(10) = -6
