What is the measure of angle 1

Mathematics
1 answer:
sashaice [31]3 years ago
4 0

Answer:

C. 74

This is because the total angle measure is 360 degrees

1.360-90 because we see a 90 degree angle here

2. 270-109=161

3.161-87=74

answer 74

16 gal = 200 mi
X gal = 350

16/200 = X/350

Cross multiply divide

16(350) = 200(X) > 5600 = 200X

Solve for X

5600/28

X = 28

shannon said that a triangle with exactly 2 congruent sides and an obtuse angle is an equilateral obtuse triangle. describe her
kolezko [41]
Equilateral means that the 3 sides are equal length. For this to happen, the triangle needs to also have 3 equal angles, but it is mentionned that it has an obtus angle, therefore, not all angles are the same, meaning the 3 sides also aren't equivalent.

the triangle isn't equilateral

A. The solution is (−2,−3)
Cerrena [4.2K]

Answer:

  D.  (-3, -2)

Step-by-step explanation:

The equations have different coefficients for x and y, so will have one solution. The solutions offered are easily tested in either equation.

Using (x, y) = (-2, -3):

  x = y -1  ⇒  -2 = -3 -1 . . . . False

Using (x, y) = (-3, -2):

  x = y -1  ⇒  -3 = -2 -1 . . . .True

  2x = 3y  ⇒  2(-3) = 3(-2) . . . . True

The solution is (-3, -2).

__

If you'd like to solve the set of equations, substitution for x works nicely.

  2(y -1) = 3y

  2y -2 = 3y . . eliminate parentheses

  -2 = y . . . . . . subtract 2y

  x = -2 -1 = -3

The solution is (x, y) = (-3, -2).

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
tino4ka555 [31]

Answer:

4x^{2}-16x+8

Step-by-step explanation:

4(x - 2)(x - 2) - 8 = 4(x^{2} - 4x + 4) - 8 = 4x^{2} - 16x + 16 - 8 = 4x^{2} - 16x + 8.
