Answer:
y =3x-7
Step-by-step explanation:
y - 2 = 3(x-3)
y -2 = 3x -9
y = 3x-7
the answer to your question is
−3x+y=−7
Answer:
- C.) obtuse triangle
- 39°
- 167°
- D.) 111°
Step-by-step explanation:
1. The sum of angles in a triangle is 180°. The sum of the given angles is less than 90°, so the remaining angle must be more than 90°. When the largest angle is more than 90°, it is an obtuse angle. A triangle with an obtuse angle is classified as obtuse.
__
2. The sum of the interior angles is 180°, so we have ...
x° +39° +102° = 180°
x° = 39° . . . . . . . . . . . subtract 141°
__
3. The third interior angle is the supplement to the sum of the given interior angles. Likewise, x° is the supplement to the third interior angle, so its value is the same as the sum of the two given interior angles. (The rule is often stated as "an exterior angle is equal to the sum of the remote interior angles.")
x° = 130° +37°
x° = 167°
__
4. Same deal as problem 3:
x° = 75° +36°
x° = 111°
Answer:
The correct answer is option A. √3
Step-by-step explanation:
From the figure we can see that aright angled triangle.
Points to remember
If a right angled triangle with angle 30°, 60° and 90° then the sides are in the ratio, 1 : √3 : 2
<u>To find the length of side opposite to 30°</u>
Let 'x' be the side opposite to the 30°, the we can write,
x : 3 : Hypotenuse = 1 : √3 : 2
Therefore x = 3/√3 = √3
The length of side opposite to the 30° is √3
The correct answer is option A. √3
