See the attached image to see the alternate interior angles that are congruent (due to the parallel horizontal lines)

tan(angle) = opposite/adjacent
tan(31) = y/400
400*tan(31) = y
y = 400*tan(31)
y = 240.344247611024 <<-- use a calculator; make sure you are in degree mode
y = 240.3

Answer: 240.3

To convert a temperature from degrees Celsius to degrees Fahrenheit, you can use the formula F= (C*1.8) + 32 where F is degrees

asambeis [7]

Answer:

The temperature is $50^{\circ}F$

Step-by-step explanation:

Given

$F= (C*1.8) + 32$

Required

Find F when $C = 10$

$F= (C*1.8) + 32$

Substitute 10 for C

$F = 10 * 1.8 + 32$

$F = 18 + 32$

$F = 50$

Help please!!!!!! 12-13 8th grade math!!!

marin [14]

Answer:

12.

m∠ACB = 180° - 58° - 78° = 44°

m∠DCE = 180° - 85° - 60° = 35°

m∠BCD = 180° - 44° - 35° = 101°

13.

Base on the picture, we know that:

x° + 2x° + 3x° = 180°

6x° = 180°

x° = 180° ÷ 6 = 30°

=> m∠K = 2x° = 2 × 30° = 60°

=> m∠L = 3x° = 3 × 30° = 90°

=> m∠KML = x° = 30°

m∠LMN = 60° + 90° = 150°
