Answer:

y $\sqrt{5}$

Step-by-step explanation:

Like radicals are radicals that have the same radical (the number into the square root) and the same radicand (the number above the root)

Here, only the last expression $\sqrt{5}$ can be chosen.

What is the measure of angle c? (Brainliest and Bonus points for best answer)

k0ka [10]

Answer:

$\displaystyle 65°$

Step-by-step explanation:

Angle b and 135° form a linear pair, so when summing them up to 180°, you will have 45° left over:

$\displaystyle 180° = 135° + m∠b; 45° = m∠b$

Now, by the Vertical Angles Theorem, angle a and 70°, in this case, are to be in congruence with each other, so you have that.

Now you must find the the measure of angle c sinse you have already found the measure of two angles already:

$\displaystyle 180° = 45° + m∠c + 70° → 180° = 115° + m∠c; 65° = m∠c$

I am joyous to assist you at any time.

Steve puts an 18-foot ladder against his house. The ladder reaches a height of 15 feet on the house. How far is the bottom of th

krek1111 [17]

Answer:

$3 \sqrt{11}$

Step-by-step explanation:

Since we are given the hypotenuse which is 18 since it slanted, and leans on the house. And we are given one of the legs which is 15 since it is vertical. We can use the pythagorean theorem to solve for this problem.

${a}^{2} + {b}^{2} = c {}^{2}$

where a and b are the legs and c is the hypotenuse l.

Let plug it in

${a}^{2} + 15 {}^{2} = {18}^{2}$

${a }^{2} + 225 = 324$

${a}^{2} = 99$

$a = \sqrt{99}$

$a = \sqrt{9 \times 11}$

$a = 3 \sqrt{11}$

Please help with this math question guys! Thank you!

Oxana [17]

Answer:

It’s b.

Step-by-step explanation:

To get the slope of the line, you need to points. Two points you already have are (0,0) and (-5,6). So all you need to do is plug those points into slope equation (y1-y2 over x1-x2) 0-6 over 0+5 equals -6/5. The slope equals -6/5, and when you plug it into y=mx+b it equals y=-6/5x. Which is b.
