8:128 = 1:4

12:48 = 1:2

Step-by-step explanation:

117/13 = 9

√9 = 3

125/5 = 25

√25 = 5

128/8 = 16

√16 = 4

Answer:

70

Step-by-step explanation:

180 -(60+65) = 180 - 125 = 55

180 - (50 + 55) = 180 - 105 = 75

180 - (35 + 75) = 180 - 110 = 70

∆ ABC is isosceles with AB= AC= 7.5cm and BC= 0 cm .the height AD from A to BC, is 6cm . find the area of ∆ ABC what will be the
lora16 [44]

I have attached an image of the triangle.

BC = 9 cm

Answer:

CE = 7.2 cm

Step-by-step explanation:

In the attached triangle, we see that;

AB = AC = 7.5cm

BC = 9 cm

AD = 6cm

BC = 9cm

Formula for area of triangle is given as;

A = ½bh

Where b is base and h is height.

For the ∆ ABC with BC as base,

Area = ½ × 9 × 6 = 27 m²

Similarly, For ∆ ABC with AB as base,

Area = ½ × 7.5 × CE

Now, area from earlier is 27 cm²

Thus;

½ × 7.5 × CE = 27

Multiply both sides by 2 to get;

7.5CE = 54

CE = 54/7.5

CE = 7.2 cm
