Answer:
11. a)50 12. a)40
Step-by-step explanation:
sum of all three angles of trinagle=180
so
111.
80+50+x=180
130+x=180
x=180-130
x=50
12.
60+90+x=180
150+x=180
x=190-150
x=40
Answer:
Step-by-step explanation:
The answer to your question is -40
Answer:
0.9950 to the nearest ten thousandth.
Step-by-step explanation:
We use the identity sin^2 t = 1 - cos^2 t
sin^2 t = 1 - (0.1)^2
= 0.99
So sin t = 0.9950 (answer).
