Answer:
8.86 ( 3 S.F)
Step-by-step explanation:
Using Sine Rule,
AB/ Sin (41) = 13.5/ Sin (90)
AB = 8.856796891
= 8.86 cm (3 s.f.)
Answer:
1. x + y = 180
2. x = 50 y= 130
Step-by-step explanation:
They're parallel.
We can label the unamed angle z.
So z = y
and 50 = x
There's 360 degrees in a circle, so x + y= 180 because it's half 360 and half a circle.
x=50
so 50 + 50 = 100.
360 - 100 = 260
so 260 ÷ 2 = 130
y = 130 because y and z are equal so they're the same number
