Answer:

x°= 55°

Step-by-step explanation:

First, find the degrees of the larger triangle.

Since every triangle equals 180° degrees, make an equation.

60°+90°+a°= 180°

Now, add the degrees together.

120°+a°= 180°

Then subtract from both sides.

120°+a°= 180°

-120 °      -120°

a°= 60°

Now that you know the sum of all the angles, subtract 25° from 60°(which is the measure of a).

60°-25°= 35°

Now that we have the measurement of the angle from the smaller triangle inside the larger one, make an equation.

35°+90°+x°= 180°

Then, add the degrees.

125°+x°= 180°

Subtract from both sides of the equation to get the answer for the variable.

125°+x°= 180°

-125°       -125°

x°= 55°

5 roach motels per square yd

A = L * W
A = 7 * 4
A = 21 square yds

so if they set out 5 roach motels per square yd, then they need to set out :
5 * 21 = 105 roach motels <==

Find x using the picture below.
Katen [24]

Answer:

x ≈ 14.5

Step-by-step explanation:

A = x²√(25+10√5)/4

A = 1.72a²

x² = A/1.72

= 363.27/1.72

≈ 211

x = √211

≈ 14.5

Brian irons 2/9 of his shirt in 3 3/5 minutes. At this rate, how much of his shirt does he iron each minute?
vodka [1.7K]

The speed for which Brian iron the shirts is given by:

R = \frac{\frac{2}{9}}{3\frac{3}{5}}

Rewriting we have:

R = \frac{\frac{2}{9}}{\frac{18}{5}}

R = \frac{10}{162}

Then, for each minute, we have the amount of ironed shirt is:

(\frac{10}{162})(1) = \frac{10}{162}

Answer:

At this rate, Brian plans 10/162 of his shirt.

What is the slope of the line ?
svetlana [45]

Answer:

y = -3x + 4

Step-by-step explanation:

y = 4, this is where your line intersects with the y axis.

x = 1 is where your line is on the x axis (you want to include the part of the line that hits a point straight on, not one that goes past it.) So when it lands on the corner of the grids like the 4 for the y axis does, that is the point you are going to use.

Rise/Run is then your equation, so since you go down 3 and over 1 (counting from your y axis point), your slope is -3/1 or -3.

Then goes your y axis, so the final equation is

y= -3x + 4

I hope this helped!
