Find the measure of acute angle of a right angle triangle when one angle is 60°
2 answers:
Answer:
30 degrees.
Step-by-step explanation:
Let the acute angle be x.
Then as the 2 acute angles in a right triangle sum to 90 degrees,
x = 90 - 60
= 30.
<h2>Answer:</h2><h3>30°</h3><h3>Explanation:</h3><h3>What we know:</h3>
- We know that all angles in a triangle add up to 180°
- We know that 1 of the 3 angles is 90°
- We know that 1 one of the 3 angles is 60°
<h3>What to find out:</h3>
- What the last angle equals
We used the information we know to give us this equation.
90°+60°+x=180°
We add 90° and 60° to give 150°
150°+x=180°
<h3>x must therefore be 30°</h3>

THE ANSWER WOULD BE X=2/3
Y = x^2 + 8x - 3
y = x^2 + 8x + (8/2)^2 - 3 - (8/2)^2
y = x^2 + 8x + 16 - 3 - 16
+ 12 - 4 + 3 - 15
= 12 + 3 - 4 - 15
= 15 - 19
= - 4
Answer:
(2, -8)
Step-by-step explanation:
(x, y)=(-3, -1)
(x1+x2)/2=-3,
(y2+y2)/2=-1,
-------------------
(x1+x2)/2=-3
(y1+y2)/2=-1
---------------------
x1-8=-6
x1=2
----------
y1+6=-2
y1=-8
(2, -8)
