Find the value of x, y and z

Mathematics
1 answer:
tangare [24]3 years ago
7 0

Answer:

Step-by-step explanation:

8x = 9x - 7

-x = -7

x = 7

9(7)-7= 63-7=56

8(7)= 56

13y+7+56=180

13y+63=180

13y=117

y=9

13(9)+7= 117+7= 124

5y-11+56=90

5y+45=90

5y=45

y=9

5(9)-11+9(7)-7= z

45-11+63-7=z

34+56=z

90=z

You are expected to know (-x)*(-x) = x^2 = (x)*(x) for any value of x.

With this in mind, you expect to be looking for squares in answer to your question. You will find them.

The legs of a right triangle measure
scZoUnD [109]

Answer:

108 in²

Step-by-step explanation:

Given that the legs of a right triangle are 12" and 18".

Be cause it is a right triangle (with 90 degrees between the legs), we can arbitrarily assign one of these to be the height and the other value automatically becomes the base.

Let 12" be height and 18" be base

area = 1/2 x height x base

= 1/2 x 12 x 18

= 108 in²
