500 KM because 150•100 (150 x 100/30 that's the total) 15,000/30=500 KM hope his helps
Answer:
complementary angles, x=19
Step-by-step explanation:
since the two parts of the angle add up to 90, they are complementary angles.
you can find x by adding them and setting it equal to 90:
3x-2+2x-3 = 90
5x-5 = 90
5x = 95
x = 19
Answer:
angle 17 is 90°.
Step-by-step explanation:
every angle there is a right angle and a right angle is 90°.
Have a nice day! :-)
Part 1)
we know that
the property of cyclic quadrilaterals for which opposite angles are supplementary
then
m∠A°+43°=180°------------> m∠A=180°-43°=137°
the answer is m∠A=137°
Part 2) <span>Quadrilateral ABCD is inscribed in a circle. What is the measure of angle A?
we know that
</span>the property of cyclic quadrilaterals<span> for which opposite angles are supplementary
then:</span>
<span>m∠A+m∠C=<span>180<span>∘
(2x+9)+(3x+1)=180---------------> 5x+10=180
x=(180-10)/5=34
</span></span></span>m∠A=2x+9-------------> 2*34+9=77°
<span>
the answer is </span>m∠A=77°<span>
