T=34.34
explanation: solve for t by simplifying both sides of the equation, then isolating the variables.
I assume you're familiar with the limit

for

. We write the given limit in this form:

The limit on the RHS is 1, so we're left with -2.
Answer: A, 39
Explained: tan(x) 8/10 = 38.7 which is then rounded to 39
The first one is -12 the second is 10
Triangles equal 180°. The bottom left corner is 90° in this triangle. Add the angles together set equal to 180°.
x= unknown angle
90° + 67° + x= 180°
157 + x= 180
subtract 157 from both sides
x= 23°
ANSWER: x=23°
Hope this helps! :)
