Answer:
a = 7, b = 
Step-by-step explanation:
Using the sine ratio in the left right triangle and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
a ×
= 7
( divide both sides by
)
a = 7
--------------------------------------------------------
Using the tangent ratio in the right triangle on the right and the exact value
tan60° =
, then
tan60° =
=
=
=
( multiply both sides by b )
b ×
= 7 ( divide both sides by
)
b =
×
= 
Answer:
C. 111
Step-by-step explanation:
10^0 is 1 because of the exponent rule for 0 which is x^0 = 1, 10^1 would be just "10" and 10^2 would be "10x10" which is 100, adding these up would be 1 + 10 + 100 which equals 111
