The options are;
A) b + c = 90
B) 90 + c = 180
C) b + c = 180
D) 42 + b = 150
Answer:
C) b + c = 180
Step-by-step explanation:
From angle theorems, we know that sum of angles on a straight line is 180°
Now, c and 42° form a straight line.
Thus;
c + 42 = 180°
c = 180 - 42
c = 138°
Similarly b and c form a straight line and so;
b + c = 180°
From the given options, the only correct one is Option C.
18 is 60+35=95 180-95= 85 so ?=85°
Answer:
33.0
Step-by-step explanation:
Using the pythagoras theorem
tan theta = opposite/adjacent
tan 41 = x/38
x = 38tan41
x = 38(0.8693)
x = 33.03
Hence the value of x to nearest tenth is 33.0
