Answer:
the answer is b . 0.4405 which is 0.44
Step-by-step explanation:
just divide and subtract
Answer:
x ≤ 39/5
Step-by-step explanation:
To solve for the inequality, isolate the x variable.
5x - 7 ≤ 32
Add 7 to both sides.
5x ≤ 39
Divide both sides by 5.
x ≤ 39/5
Answer:
The two shorter sides have to be equal and the two longer sides have to be equal.

Answer:
The three angles of the right-angled triangle are
a = 35°
b = 90°
c = 55°
Step-by-step explanation:
We are given the ratio of angles of a right-angled triangle
a:b:c = 7:18:11
Recall that the sum of interior angles in a right-angled triangle is always 180°
7x + 18x + 11x = 180
36x = 180
x = 180/36
x = 5
a:b:c = 7x:18x:11x
a:b:c = 7(5):18(5):11(5)
a:b:c = 35:90:55
a = 35°
b = 90°
c = 55°
Alternatively:
We are given that the smallest angle is 35°
a = 7x = 35
x = 35/7
x = 5
b = 18x
b = 18(5)
b = 90°
c = 11x
c = 11(5)
c = 55°
