Find the measure of the missing angle in this isosceles triangle.

Answers

The measure of the missing angle(a) in the isosceles triangle(two sides and angle equal) is 70 degrees.

What is an Isosceles triangle?

An Isosceles triangle is a triangle that has two of it sides equal to each other and two of it angles equal to each other.

The base angle of an isosceles triangle are equal. Therefore, let's find angle a in the triangle.

55 + 55 + a = 180

Recall the sum of angle in a triangle is 180 degrees.

110 + a = 180

subtract 110 from both sides

110 - 110 + a = 180 - 110

a = 70 degrees

Step-by-step explanation:

Firstly, I made the mixed number an improper fraction; 5/4

Then I did the equation;

5/1 x 5/4 = 25/4

25/4 is 6.25 when divided, then made it a fraction; 6 1/4

Jay is measuring the angles of a triangle. He gets 30 degrees and 100 degrees, what is the measured third angle?

Answers

Answer:

50°

Step-by-step explanation:

the sum of the 3 angles in a triangle = 180° , that is

3rd + 30° + 100° = 180°

3rd + 130° = 180° ( subtract 130° from both sides )

3rd angle = 50°

Answer:

50 degrees

Step-by-step explanation:

In any triangle, there are 180 degrees. If we add 100 degrees plus 30 degrees to get 130, simply subtract that from 180 the get the measure of the third angle. (180-130= 50) Hope this helps!

What is the solution to the equation t minus 15 = 76?
t minus 15 = 76. t minus 15 minus 15 = 76 + 15. t = 91.

t minus 15 = 76. t minus 15 + 15 = 76 + 15. t = 91.

t minus 15 = 76. t minus 15 minus 15 = 76 minus 15. t = 61.

t minus 15 = 76. t minus 15 + 15 = 76 minus 15. t = 61.

Answers

Answer:

$25,626.53

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 8.5% into a decimal:

8.5% ->  -> 0.085

Now lets plug in the values into the equation

Lastly, subtract the total from the initial balance:

Answer:

Approximating has always been an important process in the experimental sciences and engineering, in part because it is impossible to make perfectly accurate measurements. Approximation also arises because some numbers can never be expressed completely in decimal notation. In these cases approximations are used.
