Step-by-step explanation:
it's an Equilateral triangle
the base angels are equal
A=100°
B=40°
C=40°
The formula to convert degrees Fahrenheit to Celsius is:

Convert 59°F to degrees Celsius.
Add the number 59 in the formula, and solve.

Subtract 32 from 59.

Multiply 5 x 9 = 135, then divide 135/9 = 15.

Therefore 59 °F = 15 °C. The correct option is "D".

Answer:
25%
Step-by-step explanation:
The average cost of the automobile in 2013 is $16,000
The present cost now is $20,000
Therefore the rate of increase between the two automobiles can be calculated as follows
= 20,000-16,000/16,000
= 4,000/16,000
= 0.25×100
= 25%
Hence the rate of increase is 25%
Answer:
2.3
Step-by-step explanation:
2 2/3 × X= 6 1/7
8/3 × X= 43/7
8x/3 =43/7
cross multiply;
56x=129
Divide both sides by 56
56x/56= 129/56
x= 2.3036=2.3
