Answer:

x = 40

Step-by-step explanation:

→ Add all the angles together

3x + 2x + 5 + 2x + 10 + 2x - 15 ⇒ 9x

→ Make the equation equal to 360°

9x = 360°

→ Divide both sides by 9

x = 40

Answer:

x=40

Step-by-step explanation:

Sum of angle measure- 360°

Therefore all 4 four of them should be equal to 360-

2x+5+3x+2x+10+2x-15=360

Simplify the equation-

9x=360

Make x by itself-

x=360÷9

x=40

Help with some math homework? The area of a triangle is 110 square inches. the height of the triangle is 8 less than 3 times its
Alenkasestr [34]
A = h x b; where A = area of a triangle; h = height of the triangle; b = base of the riangle;
So, we have the equation : 110 = (3b - 8)b;
We solve the equation 3b^2 - 8b - 110 = 0;
The positiv solution  is b = 7.53 cm;
h = 3 x 7.53 - 8;
h = 14.59 cm;
