It is an equilateral triangle, so the angles need to add up to 60 degrees each
5y = 60
5y/5= 60/5
y = 12
2x - 4 = 60
2x - 4 (+4) = 60 (+4)
2x = 64
2x/2= 64/2
x = 32
hope this helps (this is assuming it is a equilateral triangle)
Answer:
Shaded = 12 cm^2 Unshaded = 1.96 cm^2
Step-by-step explanation:
<u>This is really an </u><u>impossibly</u><u> out- of- scale drawing :</u>
<u> (assuming if it </u><u>LOOKS</u><u> like a right angle it </u><u>IS</u><u> a right angle ) </u>
Other side of large <u>rectangle</u> (via pythagorean theorem):
= sqrt (8^2 - 5^2) = sqrt 39
Large <u>rectangle</u> area = 5 x sqrt39 = 13.96 cm^2
Small shaded rectangle = 4 x 3 = 12 cm^2
UNshaded area = large area - shaded area = 13.96 - 12 cm^2 = 1.96 cm^2
Answer:
-1/3 is the slope
Step-by-step explanation:
Slope formula: y2-y1/x2-x1
-2+1 / 3-0= -1/3
The answer should be c- 52
