Answer:
C
Step-by-step explanation:
Because and both lie on a straight line, they sum to .
So, .
We can subtract from both sides of the equation to get .
So, the answer is and we're done!
Answer:
GE = 14
Step-by-step explanation:
The incenter is equidistant from the sides, so GD = GE = GF.
Set the expressions for GD and GF equal to each other and solve for x.
3x + 5 = 6x - 4
5 = 3x - 4
9 = 3x
3 = x
Now plug this value into either expression, say for GD. GD = 3(3) + 5 = 14.
GE must be the same, GE = 14
Im not 100% sure but
1.square root of 0.4
2. -7.888888888888
Answer:
<h3>
The sum of m∠Q and m∠S must be equal 90°</h3>
Step-by-step explanation:
The measure of right angle is 90°
The sum of measures of angles in any triangle is 180°
so:
m∠Q + m∠S + ∠R = 180°
m∠Q + m∠S + 90° = 180°
m∠Q + m∠S = 180° - 90°
m∠Q + m∠S = 90°
