The sum of two angles in a triangle is 87 what is the measure of the third angle

Reil [10]

Answer: 93 degrees

Step-by-step explanation: The 3 angles of a triangle always add up to 180. Two angles are 87 and to find the third angle, you subtract 180 by 87 and get your third angle which is 93.

Please help I have no idea how to do this!!!

Ronch [10]

Answer:

You have to graph and label the points

Step-by-step explanation:

3x-5 is just a straight line which is lesser than or equal to -1 so that is a closed circle

-2x+3 is another straight line which is (both open circle) which its domain is restricted from -1 to 4

2 is just a horizontal line starting at (closed circle) 4, it is greater than also.

If you don't understand the the constants (the numbers on their own) just a vertical translation.

If the cross either the x or y axis, you have to find that too, im pretty sure.

To find the y axis intercept, make x = 0 and solve for y

and to find the x axis intercept, make y = 0 and solve for x

0.15(y-0.2)=2-0.5(1-y)<br><br> The answer is -153/35 I just need to know how to get that

butalik [34]

Answer:

$y=-\dfrac{153}{35}$ .

Step-by-step explanation:

The given equation is

$0.15(y-0.2)=2-0.5(1-y)$

Using distributive property, we get

$0.15(y)+0.15(-0.2)=2-0.5(1)-0.5(-y)$

$0.15y-0.03=2-0.5+0.5y$

$0.15y-0.03=1.5+0.5y$

Isolate variable terms.

$0.15y-0.5y=1.5+0.03$

$-0.35y=1.53$

Divide both sides by -0.35.

$y=\dfrac{1.53}{-0.35}$

$y=-\dfrac{1.53}{0.35}\times \dfrac{100}{100}$

$y=-\dfrac{153}{35}$

Therefore, $y=-\dfrac{153}{35}$ .

tiny-mole [99]

The volume of a right cone is one-third of the product of the area of the base B and the

$V=\frac{1}{3}Bh$

Since the area of the base and the height is already given, substitute the values in to the equation and then simplify.

$\begin{gathered} V=\frac{1}{3}(254.3)(16.7) \\ =\frac{1}{3}(4246.81) \\ \approx1415.603 \end{gathered}$

We may also find the exact value by substituting the given values into the equation below.

$V=\frac{\pi r^2h}{3}$

where V is the volume, r is the radius, and h is the height.

To obtain the exact value of the height, we use the Pythagorean theorem.

$\begin{gathered} a^2+b^2=c^2 \\ a^2=c^2-b^2 \\ a=\sqrt[]{c^2-b^2} \end{gathered}$

where a and b are the legs of the formed right triangle while c is its hypothenuse.

From the figure, the slant height is the hypothenuse while the radius, 9 ft, serve as one of the legs. Thus, the other leg, which is the height of the cone can be solved as follows.

$\begin{gathered} a=\sqrt[]{19^2-9^2} \\ =\sqrt[]{361-81} \\ =\sqrt[]{280} \end{gathered}$

Therefore, the height of the cone is as stated above.

Substitute the obtained height and the radius into the second formula that was stated.

$\begin{gathered} V=\frac{\pi r^2h}{3} \\ V=\frac{\pi(9^2)(\sqrt[]{280})}{3} \end{gathered}$

Simplify the right side of the equation. Evaluate the exponential expression.

$V=\frac{\pi(81)(\sqrt[]{280})}{3}$

Multiply the numerator and then divide it by 3.

$\begin{gathered} V=\frac{\pi(81)(\sqrt[]{280})}{3} \\ \approx\frac{(3.1416)(81)(16.7332)}{3} \\ \approx\frac{4258.0907}{3} \\ \approx1419.36 \end{gathered}$

Note that the value that we obtain at first, 1415,603, is slightly different from the one that we obtained, which is 1419.36, since there are values that we already rounded off before substituting the values in the equation.

Therefore, to be more exact, it is best to indicate that the volume of the given cone is approximately 1419.36 ft³.
