Answer:

136°

Step-by-step explanation:

In quadrilateral ABCD,

$m\angle A = 180\degree - 107\degree = 73\degree$ (Angles in linear pair)

$m\angle B = 61\degree$ (Vertical Angles)

$m\angle C= 90\degree$ (Given)

$m\angle A +m\angle B+m\angle C+m\angle D= 360\degree$ (Interior angle sum postulate of a quadrilateral)

$73\degree +61\degree+90\degree+x= 360\degree$

$224\degree+x= 360\degree$

$x= 360\degree-224\degree$

$x= 136\degree$

Use the multiplication property of exponents to determine if each statement is true or false.

lisabon 2012 [21]

1)
LHS:
${a}^{4} \times {a}^{3} \times a \\ = {a}^{4 + 3 + 1} \\ = {a}^{7}$
LHS = RHS. So, the statement is true

2)
LHS:
${5}^{2} \times {3}^{4} \\ = 25 \times 81 \\ = {5}^{2} \times {9}^{2} \\ = {45}^{2}$
LHS not equal to RHS. So, the statement is false

3)
LHS:
${x}^{6} \times {x}^{0} \times {x}^{2} \times {x}^{3} \\ = {x}^{6 + 0 + 2 + 3} \\ = {x}^{11}$
LHS = RHS. So, the statement is true.

4)
LHS:
$7 {m}^{2} \times 2m \times 4 {m}^{5} \\ = (7 \times 2 \times 4) {m}^{2 + 1 + 5} \\ = 56 {m}^{8}$
LHS = RHS. So, the statement is true.

LUCKY_DIMON [66]

Answer:

8 = 16

Step-by-step explanation:

1/4 = 4 /8

Cross multiply:

1 * 8 = 4 * 4

Simplifying

1 * 8 = 4 * 4

Multiply 1 * 8

8 = 4 * 4

Multiply 4 * 4

8 = 16

Solving

8 = 16
