Answer:
X= 30-4r/-6
Step-by-step explanation:
1. Move the 9 to the other side. (21+9=30)
2. subtract the 4r and move it to the other side (-6x=21-4r)
3. divide both sides by -6

Answer:
67 degrees
Step-by-step explanation:
46 + 67 + x = 180
x = 67
Answer:
54.91
Step-by-step explanation:
64.6/x=100/85
(64.6/x)*x=(100/85)*x
64.6=1.17*x (divide both sides of the equation by 1.17 to get x)
54.91=x
x=54.91
now we have 85% of 64.6= 54.91
The triangle is an isosceles triangle because of its degrees. A triangle consists of 180 degrees therefore, 180-90-45 simply makes it 45 matching the other side.
So we can assume that side b is also equivalent to side a. Here we use the pythagorean theorem to find x
a^2 + b^2 = c^2
5^2 + 5^2 = c^2
25+25=50
The square root of 50 is 7.1
x= 7.1
