Answer:
x=2 AB=hypotenus(h) angle ACB is 90
BC=p angle CAB is 30 also angle of refrence
Step-by-step explanation:
sin[30]=p/h
(1/2)=x/4
2x=4
x=2
Answer:
10
Step-by-step explanation:
Since m||n the sum of given angles is equal to 180 (they are supplementary)
6x + 10 + 10x + 10 = 180 add like terms
16x + 20 = 180 subtract 20 from from both sides
16x = 160 divide both sides by 16
x = 10
