Answer:
<em>angle ABD =</em><u><em>55 degree</em></u>
<em>angle BCD= </em><u><em>125 degree</em></u>
Step-by-step explanation:
angle ABD and angle DBC are supplementary angles.
Hence, angle ABD +angle DBC = 180 --equation 1
angle ABD = (2x+15) ---equation 2
angle BCD = (4x+45) ------equation 3
ABD+DBC=180
(2x+15) + ( 4x+45 ) = 180
2x+4x+15+45=180
6x+60=180
6x=180-60
6x=120
x=120/6=20
angle ABD= 2x+15= 2(20) +15
=40+15= 55 degree
angle BCD= 4x+45 = 4(20) +45
= 80+45= 125 degree
Hence, angle ABD =55 degree
angle BCD= 125 degree

bottom surface area Sbot = 130 in2
Answer:
no solution
Step-by-step explanation:
49^3x = 343^2x+1
49 = 7^2 and 343 = 7^3
7^2 ^3x = 7^3 ^2x+1
we know that a^b^c = a^ (b*c)
7^(2 *3x) = 7^(3 *(2x+1))
7^(6x) = 7^(6x+3)
The bases are the same so the exponents have to be the same
6x = 6x+3
Subtract 6x from each side
0 =3
This is never true so there is no solution
