A right triangle includes one angle that measures 30º. What is the measure of the third angle?
2 answers:
Answer:
The answer is C.
Step-by-step explanation:
So to get the answer add 90+30= 120
Then take 180-120=60 (which is your leftover angle)
Answer:
C. 60º
Step-by-step explanation:
A triangle is called a right triangle when one of it's angle measures 90°.
We have been given the second angle as 30°.
The angles in a triangle add up to 180°.
∴ leting the third angle to be X;
X + 30° + 90° = 180°
X + 120° = 180°
X = 180° - 120°
= 60°

then
Thus,
Answer:
x= 35
Step-by-step explanation:
opposite angles add up to 180 so:
3x-5 +2x+10 = 180
5x+5=180
5x=175
x= 35
Answer:
1.2x-1.2y
Step-by-step explanation:
Answer: y=0.60x+36.94
To find the equation we just set y equal to the 0.60 cents times x miles plus the 36.94 base fee. Any questions just ask. Cheers
