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

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !

really really sorry if i'm

-12 -5(x + 4) = 3x

-12 - 5x - 20 = 3x

-12 - 20 - 5x = 3x

-32 - 5x = 3x

    + 5x   + 5x

-32 = 8x

8         8

- 4= x
