Answer:

B

Step-by-step explanation:

When solving exponents with parenthesis around the base + sub exponent, always multiply the two exponents. Basically, when the two exponents are right next to each other, you multiply them. When you multiply 7 and 3, you get 21; therefore, the answer is 6 to the power of 23.

Segment addition, how do u solve it? Step by step.
weeeeeb [17]

Answer:

x=7  DO=25  OG=35

Step-by-step explanation:

4x-3+2x+21=60            4(7)-3                  2(7)+21

4x+2x   -3+21                 28-3=25             14+21=35

6x+18=60                     DO=25                  OG=35

60-18=42

6x=42

42/6=7

x=7

Find the value of each variable.
Harrizon [31]

Step-by-step explanation:

b is per the identity of angles on parallel lines when intersected by one inclined line the same as the 40° angle.

so,

b = 40°

due to the parallel nature of the 2 lines there is a symmetry effect for such shapes inscribed a circle. the upper and the lower triangle must be similar. and when applying a vertical line through the central crossing point, everything to the left is mirrored by everything on the right.

so, angle c must be equal to angle b.

c = 40°

and as the sum of all angles in a triangle is always 180°, d is then

d = 180 - 40 - 40 = 100°

the interior angle of the arc angle a is the supplementary angle of d (together they are 180°), because together with d they cover the full down side of the top-left to bottom-right line.

interior angle to a = 180 - 100 = 80°

due to the symmetry again, the arc angle opposite to a is the same as a.

as we know, the interior angle to a pair of opposing arc angles is the mean value of the 2 angles.

so, we have

(a + a)/2 = 80

2a/2 = 80

a = 80°

there might (and actually should) be some more direct approaches for "a" out of the other pieces of information, but that was the most straight one right out of my mind, and I don't spend time on finding additional shortcuts, when I have already a working approach.

Please help, im seriously stuck on this
Rasek [7]

Answer:

x=64

Step-by-step explanation:

the shapes are similar

since the difference between 20 and 24 is 4

then you add 4 to 60 and get 64

I don't actually know 100% that this is correct but it makes sense in my head
