Answer:
Step-by-step explanation:
Given triangle is right isosceles since one of the angles is 45°
Let the AC = x, then BC = x and AB is:
- x² + x² = 5²
- 2x²=5²
- x²= 5²/2
- x = 5/√2
- x = 5√2/2
Correct option is D
Answer:
the answers are
a) Area of triangle is 15 square inches
Perimeter of triangle is 18.5 inches.
b) Area of trapezium is 210 square cm.
Perimeter of trapezium is 61.5 cm.
c) Area of parallelogram is 21 square yards
perimeter of parallelogram is 22 yards
Step-by-step explanation:
Area of triangle is 1/2( base × height)
Area of trapezium is 1/2(p1 + p2)×height
Area of parallelogram is base × height
Answer:x=6
Step-by-step explanation:
YZ is 1/2 of EF, so the same goes for the other sides. ED is 10, so XY is 5, 5=x-1, solve for x, and you get x=6. And to verify, XY is 7.5, so DF would be double that, so 15=3(x-1), which is correct 15=3(6-1)=3(5)
-10 + 2x + 30 x 12x
= 20 + 24x
