Solve for h. Then check your solution. 2h + 6= 3h -19

1 answer:

5 0

2h + 6 = 3h -19

collect like terms

2h - 3h = -19 - 6

-h = -25

Divide both sides by -1

-h/-1 = -25/-1

h = 25

Hope this helps.

How you find 8 and 10

Fittoniya [83]

Answer:

8. X = 10.5 and 19. X = 5

Step-by-step explanation:

8. You know that a triangle interior angles should add up to 180° so:

(10x - 11) + (3x - 2) + (3x + 1) = 180

180 = 16x - 12

168 = 16x

The you divide each side by 16:

168 ÷ 16 = 16x ÷ 16

X = 10.5

10. You know that a straight line equals 180° and interior angles add up to 180° so:

1st you do 180 - 151 = 29°

2nd (11x - 1) + (20x - 3) + (29) = 180

180 = 31x + 25

155 = 31x

The you divide each side by 31:

155 ÷ 31 = 31x ÷ 31

X = 5

Last summer, Karl went to the beach every 5 days. Antonia went to the beach every 33 days. How often did they see each other at

vfiekz [6]

Asuming they started summer at the same time. The logical answer will be none, because it will take at least 165 days for the lcd(5) to overlap and there is not 165 days in a summer.

so it will be a rate of 1 for every 5 times Antonia went to the beach.

The measure of a vertex angle of an isosceles triangle is 120° and the length of a leg is 8 cm. Find the length of a diameter of

Goryan [66]

ANSWER

The length of a Diameter is 3.714

EXPLANATION

The circumscribed triangle is shown in the attachment.

We use the cosine ratio to find the altitude of the isosceles triangle.

$\cos(60 \degree) = \frac{altitude}{hypotenuse}$

$\cos(60 \degree) = \frac{altitude}{8}$

Altitude =8cos(60°)

Altitude=4cm

Let the upper half of the altitude be y cm.

Then the radius of the circle is (y-4)cm

The upper radius meets the tangent at right angles.

From the smaller right triangle,

$\sin(60 \degree) = \frac{4 - y}{y}$

$y\sin(60 \degree) = 4 - y$

$y\sin(60 \degree) + y= 4$

$(\sin(60 \degree) + 1)y= 4$

$y= \frac{4}{\sin(60 \degree) + 1}$

$y = 16 - 8 \sqrt{3}$

y=1.857

The diameter is 2y

$d = 32 - 16 \sqrt{3}$

=2(1.875)

The length of a Diameter is 3.714
