Answer:

[tex]x=60^o[/tex]

[tex]y=50^o[/tex]

Step-by-step explanation:

ΔACD

[tex]50+70+x=180[/tex]

[tex]120+x=180[/tex]

[tex]x=180-120[/tex]

[tex]x=60[/tex]

ΔABC

[tex]60+50+ACB=180[/tex]

110+ ∠ACB=180

∠ACB=180-110

= 70°

Now...

x+y+∠ACB=180°

[tex]60+y+70=180[/tex]

[tex]y+130=180[/tex]

[tex]y=180-130[/tex]

[tex]=50^o[/tex]

hope it helps...

have a great day!!

Answer:

x = 60, y = 110

Step-by-step explanation:

the interior angles of a triangle will always add up to 180.

take the angles we already have and add them, once you get your answer you have to subtract that by 180 to find the missing angle.

70 + 50 = 120

180 - 120 = 60

———————-

the line at the bottom is called a straight angle, and it’s measure is 180

the exterior angle is equal to the sum of the two opposite interior angles (50 and 60)

y = a + b

y = 50 + 60

110 = 50 + 60

hope this helped!

Alexa and Savannah are both driving along the same highway in two different cars to
a stadium in a distant city. At noon, Alexa is 600 miles away from the stadium and
Savannah is 350 miles away from the stadium. Alexa is driving along the highway at a
speed of 50 miles per hour and Savannah is driving at speed of 25 miles per hour. Let
A represent Alexa's distance, in miles away from the stadium t hours after noon. Let
S represent Savannah's distance, in miles, away from the stadium t hours after noon.
Graph each function and determine how far both Alexa and Savannah are from the
stadium at the moment they are an equal distance from the stadium.

Can u help me and if u don’t know don’t answer

A development economist is studying income growth in a rural area of a developing country. The last census of the population of this area, several years earlier, showed that mean household annual income was 425 dollars, and the variance of household income was 2500 (dollarssquared). A current random sample of 100 households yields a sample mean income of $433.75. Assume that household annual incomes are approximately normally distributed, and that the population variance is known still to be 2500. Test the null hypothesis that population mean income has not increased ( H0 : "m"(greek letter) greater than equal to< 425 ) against the alternative hypothesis that it has increased ( HA :"m"(greek letter > 425 ), at a 1% level of significance.
What is the form of the rejection region?
a. Reject H0 if x < cv
b. Reject H0 if x > cv
c. Reject H0 if x < cv or if x > cv
d. Reject H0 if x = cv 3
What is the critical value?
a. 436.63
b. 433.75
c. 425
d. 437.88
What is the conclusion of the hypothesis test?
a. Accept H0
b. Reject H0 in favor of HA
