Please ASAP because i need this I use all my points

Angle A measures 120 while angle B measures 45.

Step-by-step explanation: First point to note is that the sum of the interior angles of a triangle is equal to 180. So if we have the three angles identified as

(12X + 12), 15 and (3X + 18) then we can derive the following expression;

12X + 12 + 15 + 3X + 18 = 180

By collecting like terms we now have

12X + 3X = 180 - 12 - 15 -18

15X = 135

Divide both sides of the equation by 15

X = 9

Therefore we substitute for the value of X into angles A and B in order to find the measurement of the angles

Angle A = 12X + 12

Angle A = 12(9) + 12

Angle A = 108 + 12

Angle A = 120

Angle C = 3X + 18

Angle C = 3(9) + 18

Angle C = 27 + 18

Angle C = 45

Therefore, angle A is 120 degrees while angle C is 45 degrees

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.
