Answer:
Step-by-step explanation:
The sum of a triangle's interior angles is 180
. From the figure, we can see that one of the angles is a right angle. The remaining two are x and y. By adding these together, we can equate their sum with 180.
x+y+90=180b
Using the equation found in part A and the given equation, we can form a system of equations.
Answer:
19
Step-by-step explanation:
5x² – 3x + 5
Substitute 2 in for x

Solve exponents first
5(4) - 3(2) + 5
Solve/multiply parenthesis
20 - 6 + 5
Add and subtract
