Please help I’m not good at triangle angles

Mathematics
1 answer:
wlad13 [49]3 years ago
6 0

Answer:

Step-by-step explanation:

Two of the angles are just numbers and you add them.

The third is a term and you add it along with the other two.

The total is always 180 for a triangle.

80 + 58 + 5x - 3 = 180

138 + 5x - 3 = 180              Combine on the left

135 + 5x = 180                   Subtract 135 from both sides

5x = 180 - 135                    Combine the right

5x = 45                               Divide by 5

x = 9

Solve and show work <br> What is 10% of 40
Daniel [21]
10% of 40 is 4.

1% of 40 = 40/100 = 0.4.

10% of 40 = 10.

Write 10% as a decimal number = 10% = 10/100 = 0.1

Multiply 0.1 by 40 = 0.1 × .40 = 4

9) State the coordinates of the endpoints of a<br> line segment that intersects the y-axis.
eduard

Answer:

(5,4) and (3,4)

Step-by-step explanation:

A line segment has 2 end points which can be denoted as:

(x_1,y_1) and (x_2,y_2)

When this line segment intersects at y.

This means that the coordinate on the y axis is the same at both end points

i.e.

y_1 = y_2 = y

(x_1,y_1) and (x_2,y_2) becomes (x_1,y) and (x_2,y)

x1 and x2 can be any value but the y value must remain unchanged

Using the above analysis, a possible coordinate is:

(5,4) and (3,4)

Note that there are as many answers as possible as long as the coordinate pair satisfy is of the form (x_1,y)<em> and </em>(x_2,y)<em />

Take for instance, another possible pair is:

(1,-3) and (0,-3)
