Answer:
Side a = 20.8
Side b = 20.5
Side c = 30
Side d = 2
Side e = 12.6
Step-by-step explanation:
We need to know what X is here is the equation:
3.2a+8+12.6+
+5(a+2)+(6a-3.5)=85.9
After doing the math you get a=4.
Apply this to each side and get the answer.
Side a = 20.8
Side b = 20.5
Side c = 30
Side d = 2
Side e = 12.6
<u>Check</u>
20.8+20.5+30+2+12.6=85.9
Answer:
50 deg
Step-by-step explanation:
In an right triangle, the acute angles are complementary. That means their measures have a sum of 90 deg.
m<C + m<B = 90
7x - 20 + 4x = 90
11x = 110
x = 10
m<ACB= 7x - 20
m<ACB = 7(10) - 20
m<ACB = 70 - 20
m<ACB = 50
Answer: m<ACB = 50 deg
Answer:
Step-by-step explanation:
<u>Solving quadratic equation:</u>
- 5x² - 8x + 5 = 0
- x = (-b ± √b²-4ac)/2a
- x = (8 ± √8²-4*5*5)/2*5
- x = (8 ± √64-100)/10
- x = (8 ±√-36)/10
- x = (8 ± 6i)/10
- x = (4 ± 3i)/5
x = (r ± si)/t
r = 4, s = 3, t = 5
