Because the line is flat it is 180° but since you already have one angle, 128°, you would just simply have to subtract 128 from 180 to get 52°. Your answer is 52°.

Hope this helped! ;)

a straight line in an angle is a supplementary angle which is equal to 180 degrees. Since 128 is given, you subtract the two numbers so your answer will be 52 degrees

Sammy is trying to determine how many triangles she can create out of a square grid that has a side of 14 inches. Use the image

saw5 [17]

Hello!

You first have to find the area of the square grid

To find this you multiply the sides

14 * 14 = 196

Next you have to find the area of the triangle

To find the area of a triangle you use the equation

$\frac{hb}{2}$

h is height
b is base

Put in the values you know
$\frac{7 * 14}{2}$

Multiply

$\frac{98}{2} = 49$

The area of the triangle is 49 inches squared

You divide the area of the triangle by the area of the square

196 / 49 = 4

The answer is 4 triangles

Hope this helps!

A stack of cards is numbered 1 to 21. Kelly pulls one card from the stack. What is the best approximation for the probability th

ASHA 777 [7]

The correct answer is 48%

There are 10 even numbers from 1 to 21.

That makes the probability of an even number 10 out 21.

10 / 21 x 100 = 48%
