Answer:
y = 
Step-by-step explanation:
9x-4y = 20
<u><em>Given that x = -2</em></u>
<em>Putting in the above equation</em>
9(-2) -4y = 20
-18 - 4y = 20
-4y = 20+18
-4y = 38
<em>Dividing both sides by -4</em>
y = 
y = 
y =

The measure of the angles A, B and C are 43°, 43° and 94° respectively.
Step-by-step explanation:
- Step 1: From the given details, form equations. Let ∠A and ∠B be x°.
⇒ ∠C = 51° + x°
- Step 2: Sum of angles of a triangle is 180°
⇒ ∠A + ∠B + ∠C = 180°
⇒ x + x + 51 + x = 180
⇒ 3x + 51 = 180
⇒ 3x = 129
⇒ x = 43°
⇒ x + 51 = 94°
