Answer:
length = 30 cm
Breadth = 10 cm
Step-by-step explanation:
Length = x cm
Breadth = (1/3)x
Perimeter = 80 cm
2(length + breadth) = 80
2* (x + (1/3)x) = 80
x = 30cm
length = 30 cm
breadth = 
cm
Answer: A
Step-by-step explanation: 5*5=25 it is negative so the answer is -25
Answer:
70 degrees
Step-by-step explanation:
x = angle
180 - x = it's supplement
90 - x = it's compliment
(180 - x) - 4(90 - x) = 30
180 - x - 360 + 4x = 30
reducing
3x = 210
x = 70
Answer:
-24+12(d-3)+22=-24+34(d-3)
10(d-3)
10d=-30
d=-30/10
d=3
Pythagorean Theorem is
a ²+ b ² = c ²
a and b are the shorter sides, while c is the hypotenuse, or longest side. Let’s say the side we are looking for is “b”.
Let’s first rearrange the equation, then sub in.
a ²+ b ² = c ²
b ² = c ²- a ²
b = √ (c ²- a ²)
b = √(17 ²- 15 ²)
b = √(289-225)
b = √ 64
b = 8
