If the triangles angles has the degrees of 100°and 43° what would be the next angle?

Step-by-step explanation:

Since all the angles of triangle add up to 180 degrees,

Missing angle +100 +43=180.

Let the missing angle be 'x'.

Then, x + 100 +43 =180

or, x + 143 = 180

or, x = 180 - 143 = 37 degrees

So, the next angle is 37 degrees

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50
