Answer:
52°
Step-by-step explanation:
<D = 360 - (78+106 + 124)
<D = 360 - 308
<D = 52°
Answer:
aver aver es 20 para arriba y 9 para abajo
Answer:
x/50=78/100
Explanation:
since the test has 50 points TOTAL, you know that it will be the denominator. and x would be however many points he got on the test. so out of 50 points, the student got x points is what x/50 means. then the second one would be your percentage. when converting percents do decimals, the number of your percent (in this case 78) would be your numerator, and since percents are out of 100 your denominator would be 100
Answer:
Step-by-step explanation:
The volume of the mentioned object is
Where 
is the base area, which is defined 
, because the base is a square which side is 
units long.
Additionally, we know that the volume of the object is
Replacing the first expression and the volume of the base, we have
Therefore, the expression that represents the height of the volume is
A= 28.
The formula for the Pythagorean theorem is A^2 + B^2 = C^2
So plug in what you know. A^2 + 21^2 = 35^2 you get A^2+ 441 = 1225. You then take away 441 from 1225 and you get A^2 = 784. You have to find the square root of 784 which is 28. So side A is 28.
