A is the correct answer
2 + 3i + (-1) + 7i
1 + 10i
Answer:
Step-by-step explanation:
so the steps to doing this are as follows :
Subtract the accepted value from the experimental value.
Take the absolute value of step 1.
Divide that answer by the accepted value.
Multiply that answer by 100 and add the % symbol to express the answer as a percentage.
|18.7-19.3|/19.3 = 0.031088 * 100% = 3.1%
Answer:
x=-5 & y=-2
Step-by-step explanation:
y= 3x+13
y= x-3
x-3=3x+13
-3=2x+13
-10=2x
x=-5
then
y=3(-5)+13
y=-15+13
y=-2
3x+11=65
3x=54
x=18
180-(35+65)=y
180-100=y
80=y

We know that consecutive angles in a parallelogram are supplementary, as they are consecutive interior angles between parallel lines.
Then, if we add the measure of x° and the measure of 5x° we get 180°. Then, we can write this expression and solve for x:
Then, the angle x has a measure of 30° and the angle 5x has a measure of 5*30=150°.
Answer: a. 30°, 150°, 30°, 150°
