Given: m∠EYL=72°<br> Find: mEHL , mLVE
White raven [17]

Answer:

Part 1) The measure of arc EHL is 108\°

Part 2) The measure of angle LVE is 54\°

Step-by-step explanation:

step 1

Let

x-----> the measure of arc EHL

y----> the measure of arc EVL

we know that

The measurement of the outer angle is the semi-difference of the arcs it encompasses.

so

m

we have

m

substitute

72\°=\frac{1}{2}(y-x)

144\°=(y-x)

y=144\°+x ------> equation A

Remember that

x+y=360\° -----> equation B ( complete circle)

substitute equation A in equation B and solve for x

x+(144\°+x)=360\°

2x=360\°-144\°

x=216\°/2=108\°

Find the value of y

y=144\°+x

y=144\°+108\°=252\°

therefore

The measure of arc EHL is 108\°

The measure of arc EVL is 252\°

step 2

Find the measure of angle LVE

we know that

The inscribed angle measures half that of the arc comprising

Let

x-----> the measure of arc EHL

m

we have

x=108\°

substitute

m

What is the area? Please help!!!
anyanavicka [17]

Answer: 96 ft²

Step-by-step explanation:

<u>This figure can be divided into two rectangles:</u>

  • The first rectangle has dimensions 6 ft by 14 ft.
  • The second rectangle had dimensions 4 ft by 3 ft.

<u />

<u>Find the area of both rectangles:</u>

  • The first rectangle: 6 × 14 = 84 ft²
  • The second rectangle: 4 × 3 = 12 ft²

<u />

<u>Add them together to find the total area of the figure:</u>

84 + 12 = 96 ft²
