Answer:
m∠1=80°, m∠2=35°, m∠3=33°
Step-by-step explanation:
we know that
The sum of the interior angles of a triangle must be equal to 180 degrees
step 1
Find the measure of angle 1
In the triangle that contain the interior angle 1
∠1+69°+31°=180°
∠1+100°=180°
∠1=180°-100°=80°
step 2
Find the measure of angle 2
In the small triangle that contain the interior angle 2
∠2+45°+(180°-∠1)=180°
substitute the value of angle 1
∠2+45°+(180°-80°)=180°
∠2+45°+(100°)=180°
∠2+145°=180°
∠2=180°-145°=35°
step 3
Find the measure of angle 3
In the larger triangle that contain the interior angle 3
(∠3+31°)+69°+47°=180°
∠3+147°=180°
∠3=180°-147°=33°
Answer: The coordinates of D are Option c (1,-2)
<u>explanation: </u>
The Parallelogram is a quadrilateral whose opposite sides are equal and parallel. The location of a parallelogram on a coordinate plane is determined based on its four vertices.
A coordinate plane is a two-dimensional plane formed by the intersection of two lines one is a vertical line and the other is horizontal. The vertical line is the y-axis and horizontal line x-axis.
Four points of parallelogram ABCD are A(-2,4),B(1,3), C(4,-1), D(1,-2)
Answer:
3
Step-by-step explanation:
Cube root of 27 is 3.
3³ = 27.
Answer:
2s/n-a=L
Step-by-step explanation:
So first we divide (n÷2) so it will be s/(n÷2) =a+L. Next we subtract L and get s/(n÷2)-a. That's not it yet, since 2 is being divided in the denominator, we have to reciprocal it meaning multiply, it to the top value. So it would 2s/n-a=L. But you can just leave it like that if you desire and your teacher doesn't mind.
