Question 1:
We can use the rule of exterior angle of triangle, where the exterior angle is equal to the sum of the other 2 interior angles of the triangle except for the adjacent one.
So, we can calculate angle 1 by adding up the 2 given angles.
Angle1 = 62° + 57°
=119°
=answer C.
Question 2:
We can also apply the rule above, but first we have to calculate the remaining angle of the triangle first.
For this, we have to use the angle sum of triangle. All 3 interior angles of triangle should add up to 180°.
Let that remaining angle be x.
X = 180° - 62° - 57°
X=61°
Now we can apply the rule of exterior angle of triangle.
Angle 1 = 62° + 61°
=123°
=answer D.
X= 8.29 or 8.3
you have to use the pythagorean theorem (a^2 +b^2=c^2) remember c is the hypotenuse and the hypotenuse is always across from your triangles right angle
Answer:
It has more time and the other takes less time
Step-by-step explanation:
if you subtract them it should be 4.66 seconds of difference hope this helps :)
