11) First, add 74 and 43.
74+43=117
Subtract 117 from 180. Do this because this will give you the value of angle 1. This is because the sum of the angles in a triangle will always add up to 180 degrees.
180-117=63
Angle 1 = 63 degrees
Angle 2 also equals 63 degrees, because they are vertical angles.
Angle 2= 63 degrees
Now, add 63 and 79
63+79=142
Subtract 142 from 180
180-142=38
Angle 3 = 38 degrees
12)
First, subtract 56 from 180. Do this to find angle C. They are supplementary angles, so they will equal 180 degrees.
180-56=124
Angle C=124 degrees
Now, add 124 and 20
124+20=144
Finally, subtract 144 from 180
180-144=36
The measure of angle A is 36 degrees
Hope this helped! :)
Answer:
Step-by-step explanation:
surface area=area of sides +area of top and bottom
=2(4+5)×8+2×(4×5)
=2[(9×8)+20]
=2[72+20]
=2×92
=184 m²
Answer:

Step-by-step explanation:
Multiply the original cost by .04 and 12 years
(original cost)(rate in decimal form)(time)
Answer:
y=-3/4x - 7
Step-by-step explanation:
When finding the slope given a point and a slope, we do the following.
y=mx+b (Slope-intercept Form)
m is the slope and x,y are the points
Plug in everything
-1= -3/4(-8)+b
Multiply
-1 = 6 + b
-7 = b
This gives us the final equation of y=-3/4x - 7
The answer is 1056 lmk if you need the work
