Answer:

21°

Step-by-step explanation:

we know that every single triangle has to equal 180°

we have all 3 angles 90° 34° 35° which equal 159°

so we take 180°-159° and your answer is 21°

SOMEONE HELP ME PLEASE

marin [14]

Answer:

Step-by-step explanation:

Direct variation problems can easily be solved with proportions, namely:

$\frac{x}{y} :\frac{2}{5}=\frac{4}{y}$ and cross multiply to get

2y = 20 so

y = 10

PLATO: Type the correct answer in each box. The vector is first dilated by a factor of 2.5 and then rotated by pi/2 radians. If

yawa3891 [41]

Answer:

a = -1, b = -2.5

Step-by-step explanation:

Rule for the dilation of a vector $\binom{x}{y}$ by a scale factor of k is,

(x, y) → (kx, ky)

BY using this rule for a vector $\binom{-1}{4}$ by a scale factor of 2.5

$\binom{-1}{4}$ → $\binom{-2.5}{1}$

Followed by the rotation by 90° Or $\frac{\pi }{2}$ radians,

Rule for rotation of a vector by 90° is,

(x, y) → (-y, x)

By this rule vector $\binom{-2.5}{1}$ will become,

$\binom{-2.5}{1}$ → $\binom{-1}{-2.5}$

If we represent this vector by $\binom{a}{b}$ ,

Then a = -1 and b = -2.5 will be the answer.

Find the value of r so the line that passes through the pair of points has the given slope,

aleksley [76]

Answer:

r = 14

Step-by-step explanation:

Slope = $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\$

$\frac{-4-r}{8-2}= -3 \\\\\frac{-4 - r}{6} = - 3$

Cross multiply,

-4 - r = -3*6

-4 - r = -18

-4 = - 18 + r

-4 + 18 = r

r = 14
