X=40
Y=70.
Z=70. They must add up to 180

Answer:

A. 40°

Step-by-step explanation:

As we can see it is an isosceles triangle because two sides are equal. so Base angles of an isosceles triangle are equal. Then Now.,

70° + 70° + <X = 180° {Being sum of angles of triangle }

140° + < X = 180°

< X = 180° - 140°

< X = 40°

Anthropologists approximate the height of a primate by the size of its humerus (the bone from the elbow to the shoulder) using the equation

H = 1.2L + 27.8,

where L is the length of the humerus and H is the height, in inches, of the primate.


An anthropologist estimates the height of a primate to be 60 in. What is the approximate length of the humerus of this primate? Round to the nearest tenth of an inch.

in

Answers

Answer:

26.83

Step-by-step explanation:

H=1.2L + 27.8

60=1.2x+27.8

minus 27.8 from both sides

32.2=1.2x

divide both sides by 1.2

x=26.83

The sides of a square are 4 units long. One vertex of the square is located at (-1,1) on the standard (x,y) coordinate plane. Which of the following points could also be a vertex of the square?

a. (-3,3)
b. (-5,-3)
c. (3,3)
d. (-5,3)
e. (4,5)

Answers

Answer:

There is no solution (since none has side length of 4 units)

Step-by-step explanation:

If V (-1,1) is one of vertex of a square, then the next vertex to V distance must be the known value of 4

VA: V to (-3,3)   = √(-1 - -3)² + (1 - 3)² = √8 = 2.8

VB: to (-5,-3)     = √(-1 - -5)² + (1 - -3)² = √32 = 5.7

VC: o (3,3)        = √(-1 -3)² + (1 - 3)² = √20 = 4.47

VD: to (-5,3)      = √(-1 - -5)² + (1 - 3)² = √20 = 4.47

VE: to (4,5)        = √(-1 - 4)² + (1 - 5)² = √41 = 6.4

What is the measure of angle F?

Answers

Answer:

F=140°

Step-by-step explanation:

130+120+110=360

720-360=360

40+60+20=120  360+120=480

480÷3=160  x=160

Answer:

Complementary angles, adjacent angles

Step-by-step explanation:

Which relationships describe angles 1 and 2?

Options: Complementary angles, vertical angles, supplementary angles, adjacent angles

Angles 1 and 2 are opposite to the 90° angle. So, the angles' relationship to that angles is a vertical angle, meaning that the two add up to 90°.

Complementary angles add up to 90°, so this option is correct.

Vertical angles are the pairs of opposite angles formed by two intersecting lines. Because the two angles do not follow this definition, this option is incorrect.

Supplementary angles add up to 180°. However, we know that the two add up to 90°, so this option is incorrect.

Adjacent angles are angles that are next to each other, so this option is correct.

I hope this helps! Feel free to ask any questions!

Joe wants to buy a $180 number that's on is on sale the snowboard is 30% off what is the sale price of the snowboard (show work)

Answers

Answer:

Step-by-step explanation:

Assuming that the Skateboard is $180, and you are asking for the price when it is 30% off.

180 * .70 = $126

Another way of solving the question is finding 10 % of 180, which is 18. And you are looking for 30% less, so 18 * 3 = 54, which is 30% of 180.

180 - 54 = 126

54 is the correct answer

An online media service offers video and music downloads. Each download of a song costs $1. Each download of a video costs 5 times as much as the song download. You have a credit of $70. How many songs can you purchase after buying 12 videos?

Answers

Answer:

10

Step-by-step explanation:

we can solve this using basic algebra

We set up the equation using the info that each video costs $5 and that we but 12 of them

12(1 * 5) + x = 70

(Please note: 1x = x)

12(5) + x = 70

60 + x = 70

60 - 60 + x = 70 - 60

x = 10
