I know that c is 68 because 180°=triangle by doing 50+62=112 then 180-112=68 then the base of the triangle is the same as the 31 cm so 31+31=62 that can give u a head start but i am not a high schooler but anyway HOPE IT HELPS!!!:)

Note that the interior angles must add up to 180 degrees:  50+62+m<C = 180.
Then 112 + m<C = 180, so that m<C =68 degrees.

Use the Law of Sines to find the value of a, as follows:

sin 50 deg      sin 62 deg
-------------- = ----------------
       a                  31 cm
                                                          31sin 50        31(0.766)
Then 31sin 50 = a*sin 62, and a = --------------- = ---------------- = 26.9 cm
                                                          sin 62              0.883

a =

What is the slope of the line
crimeas [40]

Answer:

gradient is equal to 0.7

Step-by-step explanation:

line passes on (-2,0) and (0,1.4)

gradient =(y2-y1)/(x2-x1)

=(1.4-0)/-(0--2)

=1.4/2

=1.4/2×10/10

=14/20

=7/10

=0.7

15.5% as simplest form
ella [17]
15.5% is the same as 15.5/100 or 155/1000, which you can take a 5 out of. 

After that, you will get 31/200

The length of a rectangular park is 20 feet longer than the width of the park. If the lenght of the park is 36 feet, what is the
lara [203]

Below is a labeled rectangle:

length = w + 20

we know length is 36 so we plug that in:

36 = w + 20

We need to isolate w and to do that we must subtract 20 from both sides:

(36 - 20) = w + (20 - 20)

16 = w + 0

w = 16

width is 16 feet

Hope this helped!

Answer:

d ≤ - 7

Step-by-step explanation:

Given

- 38d - 57 ≥ - 19d + 76 ( add 19d to both sides )

- 19d - 57 ≥ 76 ( add 57 to both sides )

- 19d ≥ 133

Divide both sides by - 19, reversing the symbol as a result of dividing by a negative quantity.

d ≤ - 7
