Step-by-step explanation:
3x+10°=70
or,3x=70-10
or,3x=60
or,x=60÷3
or,x=20
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
Answer:
b and d i think.
Step-by-step explanation:
B passes through the ordered pairs negative 3, 8 and 2, negative 7.
D passes through the ordered pairs 1, 4 and negative 4, negative 1 and is extrapolated further in the quadrant.
