Answer:

B. XZ

Step-by-step explanation:

Let's go by order of elimination!

D. Cannot be determined is incorrect because in order to determine a side you need one angle. We have three therefore, this answer would make absolutely no sense!

As for the rest we must solve!

A. XY = 62° + 55°

B. XZ = 62° + 63°

C. YZ = 55° + 63°

Add them up and see which one is the greatest!

A. XY = 117°

B. XZ = 125°

C. YZ = 118°

After adding we can determine and prove that our answer is B!

Conclusion: m∠SPT + m∠TPU = 90° Which of the statements supports the conclusion from the diagram and the GIVEN information.

solmaris [256]

Option A and B are correct

Step-by-step explanation:

Given: The measure of m∠RPS=90°.

conclusion: m∠UPW=90°

solution: It is given that m∠RPS=90° and also m∠RPS is equal to m ∠UPW as they both form the vertical opposite angles.

Thus, m∠RPS=m∠UPW=90°.

Therefore, option A is correct.

Now, SP is perpendicular to RU and WP is perpendicular to RU, therefore Perpendicular lines meet to form the the right angles.

Therefore, m∠UPW=90°

Thus, option B is correct.

Answer:

$\large\boxed{-\dfrac{5}{8}+\dfrac{1}{4}=-\dfrac{3}{8}}$

Step-by-step explanation:

$-\dfrac{5}{8}+\dfrac{1}{4}=\dfrac{1}{4}+\left(-\dfrac{5}{8}\right)=\dfrac{1}{4}-\dfrac{5}{8}\\\\\text{find LCD:}\\\\8=2\cdot4,\ \text{therefore. LCD(4, 8) = 8}\\\\\dfrac{1}{4}=\dfrac{1\cdot2}{4\cdot2}=\dfrac{2}{8}\\\\\text{continuing}\\\\=\dfrac{2}{8}-\dfrac{5}{8}=\dfrac{2-5}{8}=-\dfrac{3}{8}$

(-2,0) and (3,4) slope=1/3 and (2,4) SOLVE EQUATIONS FOR THEM PLEASE

andrew11 [14]

Answer: $a)\quad y=\dfrac{4}{5}x+\dfrac{8}{5}$ $b)\quad y=\dfrac{1}{3}x+\dfrac{10}{3}$

Step-by-step explanation:

Use the Slope formula: $m=\dfrac{y_2-y_1}{x_2-x_1}$

and the Point-Slope formula: y - y₁ = m(x - x₁)

a) (-2, 0) and (3, 4)

$m=\dfrac{0-4}{-2-3}\quad =\dfrac{-4}{-5}\quad =\dfrac{4}{5}$

Let (x₁, y₁) = (-2, 0)

y - y₁ = m(x - x₁)

$y-0=\dfrac{4}{5}\bigg(x-(-2)\bigg)\\\\\\y\quad =\dfrac{4}{5}\bigg(x+2\bigg)\\\\\\\large\boxed{y\quad =\dfrac{4}{5}x+\dfrac{8}{5}}$

b) m = 1/3 (x₁, y₁) = (2, 4)

y - y₁ = m(x - x₁)

$y-4=\dfrac{1}{3}\bigg(x-2\bigg)\\\\\\y-4 =\dfrac{1}{3}x-\dfrac{2}{3}\\\\\\y\quad \ =\dfrac{1}{3}x-\dfrac{2}{3}+\dfrac{12}{3}\\\\\\\large\boxed{y\quad =\dfrac{1}{3}x+\dfrac{10}{3}}$
