Answer:
(4,-3)
Step-by-step explanation:
2(5x-15) + 2(2x+7) =0
10x-30+4x+14 = 0
14x = 16
x = 8/7
Answer:
D) 44 inches
Step-by-step explanation:
Isosceles trapezoids have equal legs, which is why they are called isosceles.
Squares have equal side lengths are around, so you know that the missing side lengths to this figure are 5 in, 10 in, and 10 inches.
Add all of the given values together.
Add all of the "unknown" values together.
- 5 in + 10 in + 10 in = 25
Add these two values together.
- 19 in + 25 in = 44 inches
This answer corresponds to answer choice D.
Answer:
Option 1) 10 sides
Step-by-step explanation:
We are given a regular polygon. The sum of interior angles measure upto 1440 degrees.
Since it is a regular polygon, it satisfies the following properties:
- All the sides are equal.
- All interior angle have same measure.
Let the regular polygon have n sides.
Then, the sum of interior angle is given by:
Putting the values, we get,
Thus, there are 10 sides. The regular polygon is a regular decagon.
Answer:
ED = 6
Step-by-step explanation:
Use Pythagorean theorem to find the length of BE
100-64=x^2
x=6
because triangle BEA, and triangle DEA are congruent, the measure of BE, and DE are the same because of CPCTC
BE=DE=6
