Answer:

No, they are not similar

Step-by-step explanation:

The three triangle angles should always add up to 180 degrees.

In the smaller triangle, one angle is 90 degrees, so the other 2 angles in that triangle will equal 90 when added.

In the bigger triangle, the 2 other angles are 60 & 70 degrees, amounting to 130 degrees. This means the last angle will be 50 degrees.

In the end, these two triangle are NOT similar because one has a right angle and the other doesn't.

Answer:

  x = 1

Step-by-step explanation:

The axis of symmetry is the vertical line halfway between the zeros.

  x = (4 -2)/2

  x = 1 . . . equation of axis of symmetry

since -15/16 is a negative number, we can add both sides by 15/16 or subtract both sides by -15/16. Either way works.

p = 1/8 + 15/16

Use common denominator, which is 16:

p = 1(2)/8(2) + 15/16

p = 2/16 + 15/16

p = 17/16

17/16 is an improper fraction. If you want to use a mixed number for your answer, then:

17/16 becomes 1 1/16 (one and one-sixteenth, with 1 being a whole number and 1/16 being a fraction)

Answer:

180

Step-by-step explanation:

A = 16 + 25 + 36 + 49 + 64 + 81 = 271

B = 27 + 64 = 91

A - B = 271 - 91 = 180

Answer:

16 inch³

Step-by-step explanation:

Given that :

Length = 2 2/6 = 14/6 inches

Width = 3 3/7 = 24 /7 inches

Height = 2

The volume of a rectangular prism is given by :

Volume = Length * width * height

Volume = (14/6) * (24/7) * 2

Volume = 16 inch³

Answer:

Step-by-step explanation:

Break down the figure into a circle of diameter 7 and an 11 by 7 rectangle.

Area of circle = π3.5² = 12.25π ≈ 38.48 square meters

Area of rectangle = 11*7 = 77 square meters

Total area = 38.48+77 = 115.48 square meters

Answer:

Isosceles triangle

Step-by-step explanation:

Given

Two congruent angles and two congruent sides

Base on the given description, the concept being described is an isosceles triangle, as it has two congruent sides and two congruent angles.

If each angle measures 45 degrees each, then the third angle is 90 degrees.

This is shown below.

[tex]\theta + 45 + 45= 180[/tex] --- angles in a triangle

[tex]\theta + 90= 180[/tex]

Subtract 90 from both sides

[tex]\theta = 90[/tex]

Answer:

Number of boys = 12

Number of girls = 36

Step-by-step explanation:

Number of boys = x

Number of girls = 3*x = 3x

Total students = 48

x + 3x = 48

   4x = 48

    x = 48/4

    x = 12

Number of boys = 12

Number of girls = 3*12 = 36
