Answers:
- x = 11
- angle RQS = 106 degrees
- angle SQT = 74 degrees
===========================================================
Explanation:
Straight angles are always 180 degrees in measure.
The two smaller angles shown add up to 180
(angle RQS) + (angle SQT) = angle RQT
(9x+7) + (6x+8) = 180
(9x+6x) + (7+8) = 180
15x+15 = 180
15x = 180-15
15x = 165
x = 165/15
x = 11
From here, we then know that,
- angle RQS = 9x+7 = 9*11+7 = 99+7 = 106 degrees
- angle SQT = 6x+8 = 6*11+8 = 66+8 = 74 degrees
Note how the two results add to 106+74 = 180 to help confirm the answers.
You will need this formula:
Years = ln (Total / Principal) / rate
(where "ln" means natural logarithm)
and we'll use $100 and $200 for beginning and ending amount
Years = ln (200 / 100) / rate
Years = 0.69314718056 / .052

7932 x 56 = 444192 and since it’s asking you to multiply by .56 and 793.2, just move the decimal over to the left three places in your answer since there’s three digits after the decimals in your factors. so you get 444.192
Answer:
A solar panel is the best way to transform electrical energy into other forms of energy
Answer:
No
Step-by-step explanation:
You need a 90 degree angle to form a right triangle, as well as two other angles with the sum of 90 to be equivalent to 180 degrees.
Hope this helps!
