Answer:

1. 30°

2. [tex]1:1:\sqrt{2}[/tex]

3. 20cm

4. 5cm

Step-by-step explanation:

for the first one:

we have the triangle RVT and we know that

[tex]\angle V = 90\\\\\angle R = 60[/tex]

so [tex]\angle T[/tex] [tex]+ \angle V+\angle R[/tex] = 180

so

[tex]\angle T = 30[/tex]

for the second one

we know by specials right triangles that the sides are

[tex]x:x:x\sqrt{2}[/tex]

divide by x and get

[tex]1:1:\sqrt{2}[/tex]

for the third one

again by 30-60-90 triangle we know that

[tex]2BC=AB\\\\2(10)=AB\\\\AB=20[/tex]

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
