85 = 10x+15
70 = 10x
x = 7
180-85 = 95 = z
Answer:
°
Step-by-step explanation:
Answer:
142°
Step-by-step explanation:
90°+52°= 142°
180°-142°= 38° (angles in a triangle add up to 180°)
x= 180°- 38° (angles on a straight line is 180°)
x= 142°
a^2+b^2=c^2
0.75^2+3^2=c^2
0.5625+9=c^2
______ ____
/9.5625= /c^2

Area of a circle for (360degrees) = pi*(r^2)
Area of part of a circle with angle θ=(θ/360)*(pi*)*(r^2)
<span>(θ/360)*pi*(6^2)=12*pi
</span>solving, <span>θ=(12/36)*360
</span><span>θ=120 degress
