Answer:
the area is multiplied by 3
Step-by-step explanation:
if the diagonal is multiplied by 3 than the area will "grow larger" by 3.
Let the original price of headphone = x
there is 40% discount which is 0.40x
so the payment price will be x-0.40x = 0.60x
Given that paid amount is $36
so both will be equal
0.60x = 36
x=36/0.60
x=60
Hence final answer is $60.
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°
<h2>
Answer:y=2x-3</h2>
Step-by-step explanation:
is called solution of a equation if satisfies the equation.
Consider the equation 
,
For point 
,
So,
The point satisfies the equation.
For point 
,
So,
The point satisfies the equation.
So,both the points satisfy the equation
Answer: 25.67°
Step-by-step explanation:
Tangent = opp/adj
7/3 = 2.333
To get degrees, take tan^-1 of 2.33 25.666. round to 25.7 or 25.67°
