Pentagram's angles add up to 540. After subtracting all the other angles, you are left with 109.
Answer:
8 and yes
Step-by-step explanation:
c² - b² = a²
100 - 36 = a²
64 = a²
a = 8
the three sides form a sequence, 6, 8, 10, which is the pythagorean triple.
Answer:
10 cm
Step-by-step explanation:
we know that the perimeter of a rectangle= 2(l+w)
given that the perimeter is 46 cm and length is 13 cm, so by putting the values we get,
2(13+w)=46
= 26+2w=46 (opening the brackets)
= 2w= 46-26
= 2w=20
= w=20/2
w= 10 cm
Cheers.
Answer:
f(x) = 4x + 4
Step-by-step explanation:
When a line is parallel to another line, the slopes are always equal. Therefore, the coefficient for x has to be four. If you multiply the y-coordinate by 4, you get 4. To get 8, you have to add four, so the equation is simply f(x) = 4x+4.
