Answer:
46 degrees
Step-by-step explanation:
you know that if you add 134 and x it will equal a straight line or 180 degrees. So set it up as an addition problem.
134 + x =180 subt. 134 from both sides
x=180-134
x=46 degrees
Answer:
Step-by-step explanation:
This is what i get what i understand from your question .
Kurt earns $7 per hour for doing chores. his goal is to make at least $35 each week
So ,
$7 =per hr
X= unknown hrs
$35= goal
7 x =35
Divide both sides by 7 to get x alone representing hrs.
X= 35/7
X= 5
So 5 hrs per week to make 35 a week.
5×7=35
35=35
400 miles -----------4 hours
X miles ------------2 hours
4x=400.2
4x=800
X=200
Or
400miles --------------- 4hours
X miles --------------- 6 hours
4x=400.6
4x=2.400
X= 600
<h3>
Answer: AC = sqrt(21)/2</h3>
====================================================
Explanation:
Triangle CDA is congruent to triangle CDB. We can use the HL (hypotenuse leg) congruence theorem to prove this. This only works because we have two right triangles.
Since CDA and CDB are congruent, this means their corresponding pieces are the same length. Specifically AD = DB, so
AD+DB = AB
AD+AD = 3
2*AD = 3
AD = 3/2 = 1.5
For triangle CDA, we have AD = 3/2 = 1.5 and CD = sqrt(3). We can use the pythagorean theorem to find the missing side AC
a^2 + b^2 = c^2
(AD)^2 + (CD)^2 = (AC)^2
(3/2)^2 + (sqrt(3))^2 = (AC)^2
9/4 + 3 = (AC)^2
(AC)^2 = 9/4 + 3
(AC)^2 = 9/4 + 12/4
(AC)^2 = 21/4
AC = sqrt(21/4)
AC = sqrt(21)/sqrt(4)
AC = sqrt(21)/2
This is the same as writing (1/2)*sqrt(21) or 0.5*sqrt(21)
Answer:
store D
Step-by-step explanation:
Becuase if the Store D hast the same cost as the Store B it will be better to pick at store D because The original price is 550 for the dress meanwhile The store D have 28% off which it only cost 296$
