A triangle has a bottom left angle of (x + 15) degrees and a bottom right angle of (x degrees). 1 parallel and horizontal line s
its at the top point of the triangle. Another parallel and horizontal line sits at the base of the triangle. The exterior angle to the bottom right angle of the triangle is (4 x minus 20) degrees.
What is the value of x?
What is the value of x?
1 answer:
Answer:
<em>The value of x is 40°</em>
Step-by-step explanation:
The triangle described in the text of the question is shown in the image attached.
Note the angles x and 4x-20 are supplementary since they form a line. Thus:
x + 4x - 20 = 180
Simplifying:
5x - 20 = 180
Adding 20:
5x = 200
Solving:
x = 200/5 = 40
The value of x is 40°

Answer:
Step-by-step explanation:
We are using the formula I=PRT and calculating simple interest.
<em>I</em> is the interest, <em>P</em> is the principal or starting amount, <em>R </em> is the interest rate as a decimal, and <em>T</em> is the time in years.
We know that there is $1555.00 at 8% for 2 years. First, convert the interest rate to a decimal. Divide the rate by 100 or move the decimal place 2 spots to the left.
- 8/100 = 0.08
- 8. --> 0.8 --> 0.08
Now we know all the values:
- P= 1555.00
- R= 0.08
- T= 2
Substitute the values into the formula.
Multiply.
The account earned $248.80 in interest, but the question asks for the total amount in the account. We must add the interest to the starting amount.
After 2 years, the savings account had <u>$1803.80</u>
