Base of an isosceles triangle is 5 more than three times the equal sides and perimeter of the triangle is 75 cm. Find the length of the sides of the triangle?

14

14

47

Step-by-step explanation:

An isosceles triangle has two opposite sides. If the two angles are equal , it means the triangle is an isosceles. Because 90 degrees is greater than 45 degrees, the two sides with the same length, would have a smaller length than the third side.

5 + 3x + x + x = 75

5 + 5x = 75

5x = 70

x = 14

5 + 3(14) = 47

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

i think the answer is b
