The sides OP and RO of triangle POR are produced to points S and T respectively. If ∠SPR = 145° and ∠POT = 115° , find ∠PRO

Margarita [4]

Answer:

$\angle PRQ = 80$

Step-by-step explanation:

Given

$\angle SPR = 145^o$

$\angle POT = 115^o$

See attachment

Required

Find $\angle PRO$

First, calculate $\angle RPO$

$\angle RPO + \angle SPR = 180$ --- angle on a straight line

So, we have:

$\angle RPO + 145 = 180$

Collect like terms

$\angle RPO = 180 - 145$

$\angle RPO = 35$

Next, calculate PQR

$\angle POR + \angle POT = 180$

So, we have:

$\angle POR + 115 = 180$

Collect like terms

$\angle POR = 180-115$

$\angle POR = 65$

So, PRO is calculated as:

$\angle PRO + \angle POR + \angle RPO = 180$ --- angles in a triangle

So, we have:

$\angle PRO + 65 + 35= 180$

$\angle PRO + 100= 180$

Collect like terms

$\angle PRO = 180-100$

$\angle PRO = 80$

Please solve these two questions :) - Use the graphs to solve the equations provided.

harkovskaia [24]

Answer:

7.(1,0) and (-4,0)

8. (-3,0) and (-2,0)

Step-by-step explanation:

7.

When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are 1 and -4

(1,0) and (-4,0)

8. When the function is equal to zero, we are looking for the zeros, or the x intercepts

Where it crosses the x axis are -3 and -2

(-3,0) and (-2,0)

Factor the polynomial, if possible. If the polynomial cannot be factored, write prime. 100v2 – 324

quester [9]

Answer:

The factored form is:

$4(5v + 9)(5v - 9)$

Step-by-step explanation:

The given expression is:

$100 {v}^{2} - 324$

The Greatest Common Factor is 4:

We factor the GCF to get

$4(25 {v}^{2} - 81)$

We rewrite the expression within the parenthesis as difference of two squares.

$4(( {5v})^{2} - {9}^{2} )$

Recall that: a²-b²=(a-b)(a+b)

This implies that

$4(5v + 9)(5v - 9)$
