If Line DE is parallel to Line FG, and Line KL is perpendicular to Line DE, what is angle GCJ equal to?
Svetach [21]
∠JAL is 65° because vertical angle to ∠IAK
So angle ∠JAE is 90° - 65° (total angle measure is 90°)
∠JAE is 25°
Therefore ∠ACB is also 25° because alternate interior angles
And ∠JCG is 25° because vertical angles

(SAT Prep) Find the value of x.
Delicious77 [7]

Answer: x=40°

Step-by-step explanation:

The two triangles are congruent (I think it’s called the interior angle proof) so the bottom right angle is also 65°. All angles in a Triangle equal 180°, so 180-(75+65)=40

The sum of the areas of two circles is 80 pi
katovenus [111]
The area of a circle is A = πr^2. We let A1 And A2 the areas of the circles and r1 and r2 the radius of each, respectivley.

A1 + A2 = 80π
Substitute the formula for the area,
π(r1)^2 + π (r2)^2 = 80π

From the statement, we know that r2=2(r1).

<span>π(r1)^2 + π (2 x r1)^2 = 80π
</span>We can cancel π, we will have

5 x (r1)^2 = 80
Thus,

r1 = 4 and r2 = 8
