Answer:
y=76 degree(being vertically opposite angle)
y+x=180 degree(being linear pair)
76+x=180
x=180-76
x=104 degree
x=z(being vertically opposite angle)
104=z
therefore z=104 ,y=76,x=104
Step-by-step explanation:
(20x10)+(15x10)= y
the variable is the answer or represents it
(20x10)+(15x10)
20x10=200
+
15x10=150
=
350
no they do not have enough they need 50 more dollars in order to have enough.
Answer:
about 100 cm²
Step-by-step explanation:
The side length of the rhombus is 1/4 of the perimeter so is 10 cm. The length of half of the other diagonal will be the length of the leg of a right triangle with hypotenuse 10 and leg 7 (half the given diagonal).
d= √(10² -7²) = √51
Then the area of the rhombus is the product of this and the given diagonal:
A = (14 cm)(√51 cm) ≈ 99.98 cm²
The area of the rhombus is about 100 cm².
