Answer:

follow the steps bellow

Step-by-step explanation:

since you already have the x values it is easier,once you have the the y values you are going to plot the point the left side of the table are the x values and the right side are the y values. X values on a graph is the horizontal line or the line that goes left to right, and the y values on the graph re the line that goes vertical or up and down.

Find the measure of angle A when two angles are congruent?

erica [24]

m∡A = 70º

1) Considering that the Sum of the interior angles within a triangle is always 180º

2) We can write the following, and solve for x

x+80 + x +80 +40 = 180

2x +160 +40 = 180

2x + 200 = 180

2x =180-200

2x= -20

x=-10

3) So since angle A = x +80, we can plug it into that the value of x

m∡A = x +80º

m∡A=-10+80

m∡A = 70º

DOES ANYONE KNOW THE ANSWERS TO THESE PROBLEM, PLZ HELP!

Virty [35]

Answer:

Q.1.

Sum of angles of a triangle = 180°

∠A + ∠B + ∠c = 180

(3x - 9) + (4x + 15) + 90 = 180

3x - 9 + 4x + 15 + 90 = 180

7x + 96 = 180

7x = 84

x = 12

∠A = 3x - 9 = 3(12) - 9 = 36 - 9 = 27°

∠B = 4x + 15 = 4(12) + 15 = 48 + 15 = 63°

∠A = 27°

∠B = 63°

Q.2.

$using \ pythagoras \ theorem \\x^2 = 7^2 + (7\sqrt{3} )^{2} = 49 + 49(3) = 196\\x = \sqrt{196} = 14$

$sin y = \frac{opposite}{hypotenuse} = \frac{7\sqrt{3} }{14} = \frac{\sqrt{3} }{2} \\\\y = sin^{-1} (\frac{\sqrt{3} }{2} ) = 60$

x = 14

y = 60°

3. Given the image below, find the measure of ZYVZ, in degrees.<br> (3x + 5)º<br> N

pashok25 [27]

Answer:

∠ YVZ = 56°

Step-by-step explanation:

∠ WVZ = 90° ( given ), thus

∠ WVY + ∠ YVZ = 90, substitute values

2x + 3x + 5 = 90

5x + 5 = 90 ( subtract 5 from both sides )

5x = 85 ( divide both sides by 5 )

x = 17

Thus

∠ YVZ = 3x + 5 = 3(17) + 5 = 51 + 5 = 56°

Find the area of the

erik [133]

Answer:

Option A: 2338.3 cm² is the correct answer.

Step-by-step explanation:

Given that:

The given figure is a regular hexagon.

Length of side = 30 cm

Area of a hexagon is given by;

Area = $\frac{3\sqrt{3}}{2}a^2$

Putting a=30 in the formula

Area = $\frac{3\sqrt{3}}{2}(30)^2$

Area = $\frac{3\sqrt{3}}{2}*900$

Area = $3\sqrt{3}*450$

Area = 2338.26 cm²

Rounding off to one decimal place,

Area = 2338.3 cm²

Hence,

Option A: 2338.3 cm² is the correct answer.
