Center of rhombus bisects 90°.
Sum of angles in triangle = 180°
x + x + 14 + 90 = 180
2x + 104 = 180
2 (x + 52) = 180
x = (180 ÷ 2) - 52
x = 90 - 52
x = 38°
Answer:
The last expression is correct
Step-by-step explanation:
We have been given the following expression for simplification;
The bases of the two expressions are the same. They are both equal to 4. When multiplying numbers with the same base, we simply add their exponents. In this case our exponents are;
4 and -9
adding them we have;
4 + (-9) = -5
The simplified expression thus becomes;
1. Need distance formula to find how long it is then cut it in half to find the radius....d= 10.....r= 5
Need midpoint formula to find the center....midpoint= (-1, -1)
(h,k) in the equation of a circle is the center, "r" is the radius. When you plug in the center, you have to put the opposite signs...so......
equation of a Circle = (x - h)^2 + (y - k)^2 = r^2 = (x + 1)^2 + (y + 1)^2= 25
2. A= pi(r^2)
200.96= 3.14(r^2)
64 = r^2
r = 8
Then to find the circumference, C= 2(pi)(r) = 2 (3.14) (8) = 50.24
For 3 and 4, is there a diagram?
A quilt design uses parallelogram-shaped pieces that have a base measure of 4 inches and a height of 6 inches. If 15 pieces are used in the quilt, what is the total area of the parallelogram-shaped pieces in the quilt?
1.225 in.
2.360 in.
3.(450 in.)
4.900 in.
<span> 15*4*6 = 360 sorry but I only have the answers for number 1 and 2
</span>
I would help answer but i’m not sure about the question
