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°
This can be also written as y=-2x+2
First of all the - at the beginning = reflection across the x axis.
Then the first 2 is a vertical stretch of 2
the second 2 is a translation of 2 units up.
So
1.ref. across the x axis
2.vert. stretch of 2
3. translation of 2 units up
21/49 in simplist from would be 3/7.
Your answer is <em>3/7</em>
