1. 30°

2.

3. 20cm

4. 5cm

Step-by-step explanation:

for the first one:

we have the triangle RVT and we know that

so = 180

so

for the second one

we know by specials right triangles that the sides are

divide by x and get

for the third one

again by 30-60-90 triangle we know that

for the fourth one

here we can use excersie 3 and the ratio of XY:YC = 1:1

that means they are equal so

XY=YC

XY = 5

use this formula:

p(a\b) = p(a and b)/p(b).

take it from here.
