Find the m A. 100 B.143 C. 38 D. 25

Mathematics
1 answer:
Ainat [17]3 years ago
3 0

Answer:

143 degrees.

Step-by-step explanation:

m < A + m < B = 180 degrees. ( inside angles of a parallelogram). So:-

4x - 9 + x - 1 = 180

5x - 10 = 180

5x = 190

x = 38

So m < A = 4(38) - 9

= 143 degrees.

<span>Volume of a square = (s)(s)(s) and s=5a+4b Therefore: (5a+4b)(5a+4b)(5a+4b)= (25a^2+40ab+16b^2)(5a+4b)= (125a^3+200a^2b+80ab^2+100a^2b+160ab^2+64b^3)= (125a^3+300a^2b+240ab^2+64b^3) You just multiple the first time the second and then do so again with the combination of the first two times the second. A little cleaning up and you are left with an equation in terms of a and b.</span>
