The perimeter of the pentagon below is 10.5 units. Four sides of this pentagon have the same length, h, and the other side has a length of 1.7 units, as shown below.





What is the value of h?


A 2.2

B 3.7

C 4.8

D 8.8

Answers

Answer:

A 2.2

Step-by-step explanation:

So the perimeter is 10.5 and one side is 1.7 and the others are the same.

The Equation for the perimeter of a pentagon is P = side + side + side + side + side.

Fill it out for the sides.

10.5 = 1.7 + 4h

8.8 = 4h

h = 2.2

If sin A = cos B and the measure of angle A is 1.5 times the measure of angle B, find the measure of angle A

Answers

Answer:

[tex]A = 54[/tex]

Step-by-step explanation:

Given

[tex]\sin A = \cos B[/tex]

[tex]A=1.5B[/tex]

Required

Find A

If [tex]\sin A = \cos B[/tex]

Then:

[tex]A +B = 90[/tex]

Substitute [tex]A=1.5B[/tex] in [tex]A +B = 90[/tex]

[tex]1.5B + B = 90[/tex]

[tex]2.5B = 90[/tex]

Solve for B

[tex]B = \frac{90}{2.5}[/tex]

[tex]B = 36[/tex]

Substitute [tex]B = 36[/tex] in [tex]A=1.5B[/tex]

[tex]A = 1.5 * 36[/tex]

[tex]A = 54[/tex]

Consider the equation r + 2 = 3x – 4.
a. Solve the equation using algebra.
X=

Answers

Answer:

r/6 +2 = X

Step-by-step explanation:

We want to isolate X by itself to find its value. First transpose your -4 to the other side (note that -4 will become positive)

r + 2 +4 = 3x

r + 6 = 3x

To find the X, we get rid of the 3, so divide both sides by 3

r/3 + 6/3 = x

r/3 + 2 = x

OR

(r+6)/3 = x

Both works : )

Answer:

Step-by-step explanation:

We want to solve r + 2 = 3x – 4 for x.

This means isolating x on one side.  To do this, first add 4 to both sides, obtaining r + 2 + 4 =3x, or:

r + 6 = 3x

Finally, divide both sides by 3:

        r + 6

x = -------------

HELP ASAP GEOMETRY 10th

Answers

Answer:

m<FEG = 23°

m<FEH = 113°

Step-by-step explanation:

A diameter is always 180° to it's corresponding arc.

The circumference or full arc of a circle is 360°.

If EG is a diameter, Arc EG is 180°.

Given that Arc EF = 134°, and Arc EG = 180°.

Arc EF + Arc EG + Arc FG = 360°.

134° + 180° + Arc FG = 360°

314° + Arc FG = 360°

–314° –314°

Arc FG = 360° – 314° = 46°

The angle formed by the two chords that make the arc is ½ the measure of that Arc.

Meaning that m<feg which is the angle formed by arc FG is ½ 46° which means that m<feg = 23°.

Given that segment EH is tangent to point E.

The rule of a segment and a tangent is that the angle formed is also ½ the measure of the arc.

This means that m<FEH = ½(Arc FG + Arc EG)

m<FEH = ½(46° + 180°) = ½(226°) = 113°

His ant experiment is just one of many interesting stories from his life.6 One day he discovered ants crawling all over his kitchen shelf. Within minutes, a little jar of molasses was alive with them. He picked up the container and took out the pests.7 But one ant stayed inside, swallowing the sweet, sticky syrup and storing it in the pouch, or crop, inside her mouth. (All worker ants are females.)8 Because Mr. Franklin wanted to know if ants could communicate with one another, he gave this ant a challenge. He tied a piece of string around the mouth of the jar and hung it on a nail in the ceiling. Then he settled down to wait and watch.9 Shortly, the insect crawled up the inside of the container, over the rim, and down the side.10 But when she reached the bottom, there was, of course, no shelf! The ant dashed here and there and round and round. She zigged and zagged and eventually found the string.11 Then a fast march up, a dash across the ceiling, and a race down the wall and over the floor led her to an opening that let her out of the kitchen. She vanished.12 About thirty minutes later, Mr. Franklin spotted an army of ants moving like running water toward the wall. They swarmed up, flowed across the ceiling, and scrambled over to the nail holding the string. They lined up and marched, one after another, down the string and into the jar.13 Before long, there were two lines of ants on the string, one line tramping down to get at the sweet food, and the other line parading upward. They were carrying home globs of molasses in their crops.QUESTION:What is the main idea of the section under the heading A Founding Father?A.
