Answer:
none of the above? sorry not too sure
Answer: 41 degrees
Step-by-step explanation:
so, we know that a triangle is 180 degrees. since we know that one angle is 80 degrees, we can subtract that from the equation. now, we are trying to find what X is so that we can find the angle. here is how i did it:
i rewrote it and removed the parentheses.
4x + 1 + 4x + 19 = 100
then, i collected like terms and calculated it.
8x + 20 = 100
then, i moved the constant to the right.
8x = 100 - 20
then, i simply calculated it.
8x = 10
solution: x = 10
so, we just insert X into the angle for A. that gets us 4(10) + 1 = angle A
40 + 1 = angle A, hence angle A = 41 degrees.
The calculation of the expression “four times as large as 124+645” end up in 1141.
<u>Step-by-step explanation:</u>
- The question is asked to Express the calculation “four times as large as 124+645”.
- The given statement can be written in the expression form to perform the calculations.
Here, the phrase 'four times' represents the multiplication of 4.
⇒ “four times as large as 124+645” = 4(124) + 645
So, the first step is to multiply 4 with 124.
⇒ 4 × 124
⇒ 496
The expression is now modified as “496+645"
We know that, the final result is the addition of the two numbers 496 and 645 which is calculated as
⇒ 496+645
⇒ 1141
Therefore, the calculation of the expression “four times as large as 124+645” end up in 1141.
