Answer:
x = 5
Step-by-step explanation:
Add all of the angles together. We know that the third one is 90° because it is a right triangle and the little square indicates a 90° angle.
7x + 16 + 39 + 90 = 180
Simply.
7x + 145 = 180
-145 -145
7x = 35
/7 /7
x = 5

Answer:
When a triangle has two congruent sides it is called an isosceles triangle
Step-by-step explanation:
Answer:
FG = 47
Step-by-step explanation:
The opposite sides of a parallelogram are parallel and congruent, thus
EH = FG, that is
5z - 18 = 3z + 8 ( subtract 3z from both sides )
2z - 18 = 8 ( add 18 to both sides )
2z = 26 ( divide both sides by 2 )
z = 13
Hence
FG = 3z + 8 = (3 × 13) + 8 = 39 + 8 = 47
The circumference of a circle is equal to C=2πr
From the question, we have 615.44.
Assume that pi is equal to 3.14
Substitute and solve for r
615.44= 2(3.14)r
r= 615.44/ 6.28
r=98.4704
r=98
Therefore, the radius is about 98 units.
To check:
C=2πr
C=2 x 3.14 x 98
C=6.28 x98
C=615.44
