Answer:
x = 60°
Step-by-step explanation:
m∠EGD = m∠BGF = x°
The following m∠EGD, m∠DGC, m∠EGA lies on a straight line.
- <u>A straight line has total 180° interior angle.</u>
solve:
- m∠EGD + m∠DGC + m∠EGA = 180°
Answer:
No Real Solutions.
Step-by-step explanation:
√(x-5)=8√(x-2)
Square on both sides,
(√(x-5))^2=(8√(x-2))^2
or,(x-5)=64(x-2)
or,x-5=64x-128
or,-5+128=64x-x
or,123/63=x
Therefore, x=41/21
If you plug x=41/21 in √(x-5)=8√(x-2) you do not get equals, so the problem has no real solutions.
18.) The area of one of the triangles would be half of the area of the parallelogram, because the two triangles are congruent.
20.) The formula for the area of a parallelogram is:
A = b • h
110.5 = 13h
110.5 / 13 = 8.5
110.5 = 13 • 8.5
And because this is a measurement of the height, not the area, it is just meters (m)
So, the full answer is 8.5 m
I hope this helps!
(2)5x-y=12
3x+2y=2
10x-2y=12
3x+2y=2
13x=2
x=0.15
Answer:
-385
Step-by-step explanation:
Perhaps you want the sum of 10 terms of the arithmetic sequence ...
-16, -21, -26, ..., -61
The sum of any arithmetic sequence is the average term multiplied by the number of terms. The average term is the average of the first and last terms. Here, that is ...
((-16-61)/2)(10) = -385
