Answer:

x = 30

y = 120 degrees.

Step-by-step explanation:

Each angle in the larger equilateral triangle = 60 degrees.

The smaller triangle is isosceles so the 2 base angles are congruent.

So x = 60 - 30 = 30 degrees.

y = 180 - 2(30)

= 120 degrees.

Answer:

We see that the big triangle is an equilateral triangle, so all its angles will measure 60°. Therefore x° will be 60° - 30° = 30°, as he's the base angle of an isosceles triangle having the other base angle of 30°. y will simply be 180° - 60° (remembering that the sum of the angles in a triangle is always 180°).

25. The perimeter of a rectangle is equal to twice the sum of its length and its width. One
AlexFokin [52]

Answer:

The equation that can be used to find the width is 2(13 + w) = 42

The width of the rectangle is 8 inches

Step-by-step explanation:

The formula of the perimeter of a rectangle is P = 2(l + w), where l is its length and w is its width

∵ One  rectangle has a length of 13 inches

∴ l = 13 inches

∵ Its perimeter is 42 inches

∴ P = 42 inches

- Substitute the values of l and P in the formula of the perimeter

∵ 42 = 2(13 + w)

The equation that can be used to find the width is 2(13 + w) = 42

To find W divide both sides by 2

∴ 21 = 13 + w

- Subtract 13 from both sides

∴ 8 = w

The width of the rectangle is 8 inches

Need help its sector area
Paladinen [302]

Area of sector

=  \frac{30}{360}  \times  \pi \times  {(radius)}^{2}

=  \frac{30}{360}  \times  \ \frac{22}{7}  \times  {(12)}^{2}

=  \frac{30}{360}  \times  \ \frac{22}{7}  \times  12 \times 12

so the area = 37.71 square metre

Anvisha [2.4K]

Answer:

If you consume less energy you pay less with respect to the amount of energy you saved. If you saved 16% of total energy you should expect to lower your bill by 16%. Count how much is left -> 1900-1900*0.16=1596$
