Question

What is the value of the variable x? a.20 b.14 c.12 d.16

What is the measurement of angle zxy? a.35 b.40 c.55 d.60

Answer 1

Answer:

12°

55°

Step-by-step explanation:

∠WXY=90°

∠ZXY=∠WXY- ∠WXZ= 90° - 35°= 55°

• 4x+7°= 55°
• 4x= 48°
• x= 48°/4
• x= 12°

Answer 2

Answer:

The first question: The answer is C.12

The second question: The answer is C. 55

Step-by-step explanation:

The first question : Explanation: since WXY is 90 degrees and WXZ is 35 degrees subtract those two to get ZXY: 90 - 35 is 55

So it would like this for ZXY: 4x + 7 = 55

                                                x = 12

So your first answer would be C. 12

The second question: Explanation: Since we got the answer for X value we substitute it in the equation: 4x12 + 7 = 55

So the second answer would be C. 55
