2x+38=180
2x=142 (or x+x=142 from which 2x=142)
x=71
The unknown angles are each 71
You know this answer is logical as, since two sides are 21 it hints that we are looking at an equilateral triangle, which means two of its angles will be the same
Answer:
-75 and -77
Step-by-step explanation:
This can be wrote as 
. Combine like terms and subtract 2 from both sides to get 
. Divide by two to get 
and then add two to get -75.
Number 1:
We know that 1 quart = 4 cups. That means we need to divide 48 by 4.
What is 48 / 4=12
Number 1 is D
Number 2
We know that oz =0.0625 pounds
Well we multiply 0.0625 by 92 and get 6
Number 2 is B
Number 3
We know that 1 yd = 3 ft
We have to multiply. 3*6=18 But we have to add that one 18+1=19
Number 3 is C
Number 4
We know that 6 pounds = 96 oz from earlier and half of a pound is 8 so that means we do 96+8=104
Number 4 is A
Hope this really helped!
469 + 8346 = 8,815...is that what you needed to know?
D. y=-3/10x+1/2
Step-by-step explanation:
Using rise/run you can count the units the line moves from one point to another, from the left point to the right point the line travels down 3 and over 10 so you get -3 as your rise (it is negative because the line is traveling downwards) and 10 as your run, so your slop is -3/10. By looking at the graph you can see that your y-intercept is 1/2. SO when plugged into y=mx+b with m as -3/10 and b as 1/2 you get the equation y=-3/10x+1/2, or letter D.
