Answer:
The measure of the third angle is 117 degrees and the measure of the two equal angles is 31.5 degrees
Step-by-step explanation:
<u><em>The correct question is</em></u>
A geodesic dome is compromised of two different types of triangular panels. One of these is an isosceles triangle. In one geodesic dome, the measure of the third angle is 85.5 degrees more than the measure of either of the two equal angles. Find the measure of the three angles
we know that
An isosceles triangle has two sides and two equal interior angles
Let
x -----> the measure of the third angle
y ----> the measure of either of the two equal angles
we know that
-----> equation A
-----> equation B
substitute equation B in equation A and solve for y
![x=85.5\°+31.5\°=117\°](https://tex.z-dn.net/?f=x%3D85.5%5C%C2%B0%2B31.5%5C%C2%B0%3D117%5C%C2%B0)
therefore
The measure of the third angle is 117 degrees and the measure of either of the two equal angles is 31.5 degrees
Answer:
Step-by-step explanation:
Total interior angles in a triangle=180 degrees
That is: 3x + 10 + 5x - 1 + x =180
9x+9=180
9x=180-9
9x=171
x=171/9
x=19
Therefore
Angle A =67 degrees
Angle B= 94 degrees
Angle C = 19 degrees
Answer:
The 1st choice
Step-by-step explanation:
Let a point is defined as P(a,b).
If a>0, then point is a units right from origin and if a<0, then then point is a units left from origin.
If b>0, then point is b units up from origin and if b<0, then then point is b units down from origin.
It is given that the location of the movie theater is at (2, −3).
In the given point a=2>0 and b=-3<0.
A coordinate grid with a point at 2 units to the right and 3 units down from the origin labeled movie theater.
1.25 kg = 1250 grams
1250 : 250
÷ by 250 on both sides
5 : 1
