Angle B and angle C are complementary. If angle B is five times the size of angle C which equation can be used to find the measure of angle C?
A
5x+x=180

B
5x=180

C
5x+x=90

D
5x=90

Answers

Answer 1

Answer:

5x + x = 90

Step-by-step explanation:

5x+x=90 because complementary angles complete each other to 90 degrees

and one of the angle is stated as 5 times of other

now if we let x represent the angle then the equation would be :

5x + x = 90 degrees

Explanation:
48-28 = 20. Now 20 times 20 equals 400, now remember that number.
Now 28 times 62 equals 1,736.
Now back to 400.
400+1736 equals 2,136.

W X Y Z is a rhombus. If m

Answers

Answer:  3

=====================================================

Explanation:

We can use the SSS congruence theorem to prove triangle WZX is congruent to triangle YZX. Then that leads to angle WZX = angle YZX.

In short, we've proven that ZX bisects angle WZY. Similarly, segment WY cuts angle XYZ in half. The proof is the same idea as mentioned in the first paragraph. For any rhombus, the diagonals always bisect the angles inside the rhombus.

Also, for any rhombus, the adjacent angles are supplementary.

So,

(angle WZY) + (angle XYZ) = 180

(angle WZY) + (136) = 180

angle WZY = 180 - 136

angle WZY = 44 degrees

Then we cut this in half to get the measure of angle XZY

angle XZY = (angle WZY)/2

angle XZY = (44)/2

angle XZY = 22 degrees

Set this equal to the 10x-8 expression and solve for x.

10x-8 = 22

10x = 22+8

10x = 30

x = 30/10

x = 3

Which ordered pair is the best estimate for the solution to this graphed system of
equations:

Answers

Answer:

(2.1, -1.3)

Step-by-step explanation:

Each line represents the set of points that satisfy the equation.

That means there's only one point that satisfies both equations (and thus, is the solution) - the point where they cross.

We can see it's a bit to the right of x=2 and a bit lower then y=-1, so the (2.1, -1.3) point looks like the most plausible estimate.
