A certain triangle has 30 angle and 60 angle which much be a true statement about the triangle
Solnce55 [7]

Answer:

D

Step-by-step explanation:

The longest side is twice as long as the shortest side because lets suppose I have a triangle that has vertices with angles 30 and 60, the last one has to be 90 because the total is 180 degrees. Now for a 30 60 triangle, if the hypotenuse has a length of 2, the following ratios will hold true for the other two sides. The side that shares the 90 degrees and 60 degrees corners will be of length 1 and the side that shares the 30 degrees and 90 degrees corners (vertices) will be of length sqrt(3). This is true all the time. In this case the correct answer is that the longest side is twice as long as the shortest side because the longest side is the hypotenuse with length 2 and the shortest side will be the one that shares the 90 degrees and 60 degrees corners and is of length 1.

Find the value of x?
Kipish [7]
84 + x + 59 x + 51 =180

2x + 194 = 180

2x + 194 - 194 = 180 - 194 (subtract both sides by 194)

2x = -14

2x/2 = -14/2 (divide both sides by 2)

x = -7

In-s [12.5K]

To answer the problem, you must the formula in finding the interest and after that we will add it to the principal to get the future value.

The formula is: I = Prt

Interest = Principal x rate x time

= 200 x 0.062 x 6/12

= $6.2 is the interest for 6 six months.

 

Future Value = Principal + Interest

FV = 200 + 6.20

FV = $206.20 is the amount to be paid at the end of 6 months.
