So pretty much, 4g is 4 times g right? taking this into consideration, replace g with x1 and h with x4. Then you get 4 x 1 + 5 x 4. Since you're always supposed to multiply and then add (left to right), it would equal 4 + 20 which is 24. Good luck on your test.
Step-by-step explanation:
1: change 'sin²A' and 'cos²B' into (1-cos²A)and (1-sin²A) respectively.
2:open the brackets and put signs accordingly.
3: cancel (-1) and (+1).
4: remaining is your answer.
#1- I'm pretty sure that this one is the bottom right
#2- I'm pretty sure that this one is the top right
PLEASE CORRECT ME IF I'M WRONG!!!
Answer:
20
Step-by-step explanation:
First step is finding an angle in the rightmost triangle (angle K)
Using TOA we have
Tan(x)=4/8
x=26.565
which means that 90-26.565= 63.4349 will give us angle K in regards to the left triangle
Using this we can solve for JM
Tan(63.4349)=x/8
8tan(63.4349=x
x=16
So if JM = 16
and LM=4
take their sum to find JL
16+4=20
