Find the missing base (b1) of the trapezoid. Dimensions are in CM.
Alenkinab [10]

Answer:

b1 = 9 cm

Step-by-step explanation:

The formula for area of a trapezoid is

A = 1/2 (b1+b2) *h

We know Area = 135 CM ^2, Height = 10 CM, b2 = 18 cm

Substituting these in

135 = 1/2 (b1+18) *10

Multiply 1/2*10

135 = 5 (b1+18)

Divide both side by 5

135/5 = 5/5 (b1+18)

27 = b1+18

Subtract 18 from each side

27-18 = b1+18-18

9 = b1

Given ΔABC, AB = BC = AC . Area of ΔABC = 25 sqrt3 /4 cm. Find the perimeter of ΔABC.
zubka84 [21]
This is an equilateral triangle of height a√3/2 where a is the side length. So the area is ½a.a√3/2=a²√3/4.
So a²=25 and a=5cm. Therefore the perimeter is 3a=15cm.

How to calculate a probability
Lelu [443]
Probability is calculated by comparing the odds to a certain event occurring to the number of possible events.

P=\frac{possibility-of-an-event-occuring}{number-of-total-outcomes}

For example, take a six-sided dice number 1-6 on each side. The probability of rolling a 4 would be1 in 6 or 1/6. This is because of the six possible outcomes, rolling a 4 is only one of them.

P(4)=1/6

Now take the same dice. The probability of rolling an even number is 3/6. To see why, lets look at the total possible outcomes:

1
2
3
4
5
6

Of the 6 possibilities, 3 are even numbers.

P(even)=3/6 or 1/2
