Question

find the value of the variable and the measure of each labeled angle. x = 15 (type a whole number.) (x + 10)° = 25° (type a whole number) (4x - 35)° = □° (type a whole number.)

Explanation:

Step1: Substitute x value

We know x = 15. Substitute it into the expression for the second - angle.
$(4x - 35)^{\circ}=4\times15-35$

Step2: Calculate the result

$4\times15-35=60 - 35=25$

Answer:

25
