Answer:
33°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the 2 given angles from 180 for ∠1, that is
∠1 = 180° - (116 + 31)° = 180° - 147° = 33°
Answer:
y-intercept = -2
x-intercept = -4
Step-by-step explanation:
y-intercept is the point where x = 0. Hence,
y-intercept = -2
x-intercept us the point where y = 0. Hence,
x-intercept = -4

Answer:
Step-by-step explanation:
for y
take 30 degree as reference angle using sin rule
sin 30=opposite/hypotenuse
1/2=9/y (do cross multiplication)
2*9=y
18=y
for x
using pythagoras theorem
a^2+b^2=c^2
9^2+x^2=18^2
81+x^2=324
x^2=324-81
x^2=243
x=
x=9
Answer:
Step-by-step explanation:
1/2n - 5 = 21
1/2n = 21+5
1/2n = 26
n = 26 x 2
n = 52
Answer:
B 34
Step-by-step explanation:
The arc is 1/2 the same measure of the angle.
<y = 1/2 arc xz
<y = 1/2 (68)
<y = 34
