<h2>○=> <u>Correct option</u> :</h2><h2>

</h2><h3>○=> <u>Steps to derive correct option</u> :</h3>
Angle (p+7)° and angle (3p+1)° are a linear pair so their sum will be equal to 180°.
Which means :

Let us solve that equation to find the value of p and the two angles :







Thus, value of p = 43
Measure of angle (p+7)° :


Measure of angle (3p+1)° :



Thus, the measure of the larger angle = 130°
Therefore, the correct option is <em>(a) 130</em>
Answer:
61/60
Step-by-step explanation:
Answer:
From the attached graphic, we can see:
(SP + PR) * PR = (WQ + QR) * QR
SP * PR + PR^2 = WQ * QR + QR^2
4 SP + 4*4 = 8 * 5 + 25
4 SP + 16 = 65
4 SP = 49
SP = 49 / 4
SP = 12.25
