Answer:

1. <u>Area = ½(a + b) × h</u>

A = ½(9 + 15) × 15

A = ½ × 24 × 15

A = 12 × 15

A = 180mm².

2. <u>Area = 2(l × b) + l × b</u>

A = 2(12 × 4) + 6 × 3

A = 2 × 48 + 18

A = 96 + 18

A = 114m².

Answer:

4b) 180

4c) 114

Step-by-step explanation:

4)

<u>Area of rectangle:</u>

A = bh

A = 15*9

A = 135

<u>Area of triangle:</u>

A = 1/2bh

b = 15 - 9 = 6

A = 1/2(6)(15)

A = 45

<u>Combined:</u>

45 + 135 = 180

5)

<u>1st rectangle:</u>

A = 4*12

A = 48

<u>Middle rectangle:</u>

h = 12 - 9 = 3

A = 6*3

A = 18

<u>Last rectangle:</u>

A = 4*12

A = 48

<u>Combined:</u>

48 + 48 + 18 = 114

What is the measure of angle 3?
zheka24 [161]
Angles 6 and 8 add up to equal 180, so 2x - 5 + x + 5 = 180.  3x = 180 so x = 60.  Angle 3 is alternate interior to angle 6 which is 2(60) - 5 = 115, so angle 3 is also 115
