An equilateral triangle has sides of length 10 cm. **DIAGRAM IN PICTURE**

a. Calculate the perpendicular height, h, of the triangle.

b. Calculate the area of the triangle.

Give your answers correct to one decimal place. 10 cm 10 cm 10 cm

a. 8.7cm

b. 43.5cm squared

Step-by-step explanation:

a. draw the triangle with a side length of 10cm, and measure the height which is 8.7cm.

b. formula to find the area  of a triangle: (base into height) divided by 2 ((b x h) / 2)

the base is 10

the height is 8.7

(10 x 8.7)/2 = 87/2 = 43.5 cm squared

a=24; b=12

step-by-step explanation:

a/b=2: 1

a=2b

36/(1+2)=12

b=12

a=24

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~
