Question

If m26 is (2x - 5)º and m28 is (x + 5)º, what is mZ3?

a) 124

b) 1/2

c) q

d) 34

e) 56

Answer 1

To find mZ3, we can use the property that angles on a straight line add up to 180 degrees. Given m26 and m28, we can set up an equation and solve for x to find the value of mZ3.

Step-by-step explanation:

To find the value of mZ3, we need to use the property that angles on a straight line add up to 180 degrees.

Given that m26 is (2x - 5) degrees and m28 is (x + 5) degrees, we can set up an equation:

(2x - 5) + (x + 5) = 180

Simplifying the equation:

3x = 180

x = 60

Therefore, mZ3 is (x + 5) degrees which is equal to (60 + 5) degrees = 65 degrees.
