Check the picture below.
in the picture below, the bottom part
notice, 69° + 21° = 90°, so 21° and 69° are really complementary angles, sharing the same quadrant, meaning for any two sides of lengths say, a,b one angle will have a tangent of say b/a, then the other will have a tangent of a/b.
namely the tangent of each angle, is simply the other's tangent upside-down.
Answer:
3
Step-by-step explanation:
i used process of elimination... 1 and 2 looks unreasonable, and 4 doesn't work cus i tried it irl. i might be wrong though, don't rely on me :>
Answer:
B & C
Step-by-step explanation:
Okay I don't know much you need explained so I'm gonna explain pretty much everything. Starting off, you need to follow the PEMDAS rules. PEMDAS stands for Parentheses, Exponents, Multiplication, Division, Addition, and Subtraction. So when solving you have to do it in this order.
A-(5)(0.6)*7=21
B-(4/5)(15)+8=(0.8)(15)+8=20
C-4(8+2)/2=4(10)/2=40/2=20
D-14+4(2+3)=14+4(5)=14+20=34
If you need any clarification just lmk :)
The domain of the function would be -5
Th answer is would be D
