Question

Express x in terms of a.

Answer 1

Answer:

X=2a

Step-by-step explanation:

Given the angle is 30 implies

Tan30=a ÷base

1÷ √3=a÷base implies

Base=a √3

Using pythagoras theorem

x^2=a^2+(base) ^2

Substitute base value

X^2=a^2+3a^2

X^2=4a^2

Apply root on both sides

X=2a

Answer 2

Answer:

x= 60

Step-by-step explanation:

Total angles of a triangle = 180

ATP,

30+x+a = 180

30+90+x=180

120+x=180

x=180-120

x= 60
