Option D:
Right triangle
Solution:
Let us first define obtuse, acute right triangle and supplementary.
<u>Obtuse angled triangle:</u>
If any one of the angle in the triangle is more than 90°, then the triangle is an obtuse angled triangle.
<u>Acute angled triangle:</u>
If all the angles of the triangle are less than 90°, then the triangle is an acute angled triangle.
<u>Right angled triangle:</u>
If any one of the angle in the triangle is exactly 90°, then the triangle is a right angled triangle.
<u>Supplementary:</u>
If sum of the angles is 180°, then the angles are supplementary angles.
But this is not a kind of triangle.
In given triangle one of the angle is 90°.
Therefore, this is a kind of right triangle.
Option D is the correct answer.
Answer:
Figure D
Step-by-step explanation:
we know that
If the scale factor of the dilation is 1/2, that means the dilation is a reduction
so
the answer is between the Figure C and Figure D
but
a rotation of 180° eliminate the Figure C
therefore
The answer is the Figure D
Answer:
Evelyn monthly allowance is $187.
Step-by-step explanation:
Let the monthly allowance be 'x'.
Given:
Money taken with for shopping = 
Money spent of dress = $39.95
Also Given:
3/7 of the remainder on some accessories.
Money spent on accessories is equal to 
times Difference of monthly allowance and Money spent of dress.
framing in equation form we get;
Money spent on accessories = 
Also Given:
Money left after shopping = $30.60
Now we know that;
Money taken with for shopping is equal to sum of Money spent of dress and Money spent on accessories and Money left after shopping.
framing in equation form we get;
Combining like terms we get;
Now we will make denominator common using L.C.M
Hence Evelyn monthly allowance is $187.
