PLEASE I REALLY NEED YOUR HELP!

Mathematics
1 answer:
Ivenika [448]3 years ago
7 0

Answer:

x = 28

m∠ACD = 68°

Step-by-step explanation:

∠BAE ≅∠DAC because they are vertical angles

∠ACD = 180 - 124 = 56°

to find 'x':   56 + 2x + (180 - 4x) = 180

236 - 2x = 180

-2x = -56

x = 28

m∠ACD = 180 - 4(28)  =  180 - 112  =  68°

The following data shows rainfall in a forest, in inches, on consecutive days of a month: 2.7, 2.6, 2.4, 2.5, 2.8, 2.6, 2.7, 2.8
NARA [144]

Answer:

box plot with minimum value 2.3, lower quartile 2.4, median 2.6, upper quartile 2.7, and maximum value 2.8

that is the right answer because  we have  2.3    one time  that is minum then 2.4  two times that means lower 2.5 2 times but this is not middle because total 11 times calculation are given and middle is of 2.6 upper of 2.7 two times and maximum 2.8 two times

An angle, θ, is in standard position. The terminal side of the angle passes through the point (4, 5).
lara31 [8.8K]

Answer:

cos Θ = \frac{4}{\sqrt{41} }

Step-by-step explanation:

Given the angle passes through (4, 5 ) then the right triangle with sides 4 and 5 has hypotenuse h given by

h² = 4² + 5² = 16 + 25 = 41 ( take the square root of both sides )

h = \sqrt{41}

In relation to Θ, 4 is adjacent and 5 is opposite, thus

cos Θ = \frac{adjacent}{hypotenuse} = \frac{4}{\sqrt{41} }

PLZZZ HELP will mark brainliest!
erica [24]

Answer:

(3,8): No,  (-1,-11): Yes,  (2,7): Yes,  (0,-6): No

Step-by-step explanation:

Basically, you just substitute x and y with the numbers given.

18x - 3y = 15

y = 6x - 5

(3,8):

18(3) - 3(8) = 15

54 - 24 = 30  It is not equal to 15, so it does not work.

y = 6x - 5

8 = 6(3) - 5

8 = 13  It is not equal to 8, so it does not work.

Therefore, (3,8) is not a solution.

Try this for every pair and you will find that (-1,-11) and (2,7) are solutions.

I hope this helps!
