Did u see little square on the lines!? That hint to tell u that this is 90 degrees each. Two angles makes 180 degrees. If one angles is 90 degrees. We need to find x that can be plus to 64 to get 90 degrees
So 90=x+64
90-64=x
26=x
ANSWER FOR X IS 26
To check:
26+64=90
90=90
It correct!!!

In this case, the vector is passing through a right angle as shown with the little square on the left side. (all right angles equal 90 degrees) so you would simply subtract 64 from 90. (90 - 64 = 26) so x equals 26 degrees.

HELP asap AB=85m Find the length of Line CD

Aleks [24]

CD = x
BC = y
AB = 85
BD = BC+CD = y+x

tan(angle) = opposite/adjacent
tan(28) = BC/AB
tan(28) = y/85
85*tan(28) = y
y = 85*tan(28)
y = 45.1953016912257

tan(angle) = opposite/adjacent
tan(31) = BD/AB
tan(31) = (y+x)/85
tan(31) = (45.1953016912257+x)/85
85*tan(31) = 45.1953016912257+x
51.0731526173427 = 45.1953016912257+x
51.0731526173427-45.1953016912257 = 45.1953016912257+x-45.1953016912257
5.877850926117 = x
x = 5.877850926117

So CD is roughly 5.877850926117 meters

In a group of people, some are in favor of a tax increase on rich people to reduce the federal deficit and others are against it

jek_recluse [69]

Answer:

There will be 8 possible outcomes.

Step-by-step explanation:

(Assume that there is no other outcome such as "no opinion" and "do not know.")

3 persons are selected at random from this group and their opinions in favor or against raising such taxes are noted.

So, the number of possible outcomes are = $2\times2\times2=8$
