Answer:
x= log120/7log3
Step-by-step explanation:
7x=log3 120
7x= log120/log3/7
x= log120/7log3
let the first angle be a
then
second angle= 68+a
third angle=2a
we know
a+b+c=180 [sum of interior angle of triangle is 180]
a+68+a+2a=180
4a=180-68
a=28
Hence
first angle=28
second angle = 96
third angle =56
Answer:
-5(2x-6)+25x
-10x+30+25x
25x-10x+30
15x+30
15(x+2)
Step-by-step explanation:
The measure of angle ∠ABC is 30°
Step-by-step explanation:
The angle is formed outside of a circle by intersection of two tangents.You have intercept arcs, major arc 210° and minor arc 150°.
The formula is ;
∠ABC=1/2 (major arc-minor arc)
∠ABC=1/2(210°-150°)
∠ABC=1/2(60°)
∠ABC=30°
