Answer:

B) 9 square units

Step-by-step explanation:

Split the shape into a right triangle and a rectangle.

The rectangle is 2 by 3, so multiply 2 x 3 for the area: 6.

The triangle has a height of 3 and a base of 2. Multiply to get 6. Then divide by 2 to get: 3.

Add 6 + 3 to get 9 square units.

Hope it helps!

Please help me answer question 12

olasank [31]

Answer:

x = 81, y = 68, z = 99

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Consider the triangle on the left, then

x = 180 - (36 + 63) = 180 - 99 = 81

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

x is an exterior angle of the triangle on the right, thus

13 + y = x , that is

13 + y = 81 ( subtract 13 from both sides )

y = 68

Consider the triangle on the right

z = 180 - (13 + y) = 180 - (13 + 68) = 180 - 81 = 99
