Geometry question, please help!!

67

Step-by-step explanation:

Any four sided shape has 360 in total angles

You have two right angles=180

so your remaining angles also equal 180 because 360-180=180

set the equation: 15x+8+10x-3=180

add like terms: 15x+10x=25x  8-3=5  25x+5=180

move the five tot he other side to isolate the x: 25x=180-5  25x=175

divide 175 by 25 to get x by itself: x=175/25 x=7

plug in x: 10x-3  10(7)-3   70-3  67

the angle required = 67 degrees

36 is the final answer! : )

5050

hope this !
