Step-by-step explanation:
A=8B
A+B=180
8B+B=180°
9B=180°
B=20°
so
angle A =8×20=160°
angle B= 20°
Answer:
$51.38
Step-by-step explanation:
7.43% of 47.83=(rounded to the nearest hundredth) 3.55
7.43/100*x/47.83
x=3.55
because we are solving for x
we can also cross check by taking out the percentage
x/100*3.55/47.83
47.83x=355
x=7.42212000836
which is about 7.43%
47.83+3.55= 51.38
Answer:
x = 
; y = 2
Step-by-step explanation:
You have a 45 -45 - 90 triangle. There are two things to know"
1. The hypothenuse = leg ×
2. The legs are equal.
The hypothenuse is opposite the right angle that is "y" in this problem.
Hypothenuse = leg ×
= 
The legs are =
Therefore x =
Answer:
y = 8x+7
Step-by-step explanation:
firstly reduce the equation to an arithmetic series starting from the 0th term so:
7, 15, 23, 31, 39....
Secondly, identify the common difference: 8
we now know that the answer must contain 8x
Thirdly, form the equation 8x + c = y where y is a constant. Afterwards insert the values of any given x and y so:
8*0 + c = 7
c = 7
Thusly we now know that the series and thus equation is 8x+7 = y
