Two angles of a quadrilateral measure 200° and 50°. The other two angles are in a ratio of 2:9. What are the measures of those t

avanturin [10]

Answer:

20° and 90°

Step-by-step explanation:

Let 2x = measure of 1st angle

then 9x = measure of 2nd angle

The sum of the measures of the angles of a quad is 360

200 + 50 + 2x + 9x = 360

250 + 11x = 360

11x = 110

x = 10

2x = 20°

9x = 90°

Marysya12 [62]

$\tan( \alpha ) \: = \: \frac{h}{b}$
$\alpha \: = \: {22}^{0}$
$h \: = \: 450 \: ft$
Therefore,
$b \: = \: h \cot( \alpha )$
$b \: = \: 450 \: ft \: \times \: \cot( {22}^{0} )$
b = 450 ft × 2.47508685
b = 1,113.78908 ft
or,
b ≈ 1,114 ft.

Please help!!!!!!<br><br> y=[?]°

coldgirl [10]

Answer:

Since there are already 2 angles shown, which are 48 and 90 (indicated by the square in the bigger triangle, we can set up an equation.

48 + 90 + y = 180

138 + y = 180

-138 + 138 + y = 180 - 138

y = 42°
