Can someone please help me with this ?? im really confused but i need to pass this test!
Keith_Richards [23]

Answer:

84^{\circ}

Step-by-step explanation:

The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:

2(7x-7)=9x+21

Solving, we get:

2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7

Plugging in x=7 into 9x+21:

\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}

LuckyWell [14K]
First you would distribute through the parenthesis
-10x+2+7(5x-1)-3(-5x+1)
Then distribute
-10x+2+35x-7-3(-5x+1)
And then distribute 3
-10x+2+35x-7+15x-3
Collect like terms
