Answer:
66.3720930233
Step-by-step explanation:
H=x and b=x+10
A=hb/2 so
A=x(x+10)/2
A=(x^2+10x)/2 and A=48 so
(x^2+10x)=96
x^2+10x-96-0
x^2-6x+16x-96=0
x(x-6)+16(x-6)=0
(x+16)(x-6)=0, since x>0
x=6in, and since the base is x+10
base=16in
Answer: The exponent "product rule" tells us that, when multiplying two powers that have the same base, you can add the exponents. Adding the exponents is just a short cut! The "power rule" tells us that to raise a power to a power, just multiply the exponents.
Step-by-step explanation:
I am assuming this is a triangle.....P = a + b + c
P = 2a - 3 + 2a + 3a + 1....combine like terms
P = 7a - 2 <==
Answer:
Step-by-step explanation:
isosceles trapezoid = congruent sides in pairs and the same for the angles
<h2><u><em>
angle 1 = 32°</em></u></h2><h2><u><em>
angles 2 & 3 = 148°</em></u></h2>
the sum of the interior angles is 360°
so angle 1 = 32°
angles 2 and 3
(360 - 32 - 32) :2 = 148°
check
32 + 32 + 148 + 148 = 360°
the answer is good
