Answer:
Step-by-step explanation:
tanx=12/18
x=arctan(12/18)
tan(90-x)=12/(a+5)
tan(90-arctan(12/18)=12/(a+5)
a+5=12/tan(90-arctan(12/18))
a=12/tan(90-arctan(12/18))-5
a=3
35 is that right cuz Ik it is
?
y = 3
hope it helps and your day will be full of happiness
∠1 = 116
Find the inner angle first, the inner angle will be represented with x, also a triangle is 180 degrees, so:
57 + 59 + x = 180
116 + x = 180
subtract 116 from both sides
x = 64
So now u have the inner angle, and a straight line is also 180 degrees, so:
64 + ∠1 = 180
subtract 64 from both sides
