Both of the missing angles are 45*.
Hope I helped. :)
Answer:
1. g(x)=2x+1-3 --> g(x)=2x-2, which is also y=2x-2, so you can graph it.
Step-by-step explanation:
Question 1: If f(x) = 2x+1, then you can see that all you have to do is substitute the equation for f(x) into the g(x) equation because g(x)= f(x)-3. So, if you substitute it, the equation will be g(x) = (2x+1) -3, then you just solve the rest of the equation. Put it into slope intercept form, y=mx+b, and then graph the equation.
Sorry, I don't really understand number 2 myself, so hopefully I could help with he first one.

To see if it's a right triangle we need to determine if a²+b²=c²
(
)² + (
)² =
+
=
+
=
=
So it is a right triangle
Answer:
10²
Step-by-step explanation:
left triangle = 2 × 2 = 4 ÷ 2 = 2²
right triangle = 2 × 4 = 8 8 ÷ 2 = 4²
middle square = 2 × 2 = 4²
2 + 4 + 4 = 10²
