Question

hello guys heres a question for you

solve 4,5,6 and 7​

Answer 1

7)x= 105 ( opposite angle )
y=z = 180-105/2 = 75/2 =37.5
6) 1/3

Answer 2

$\bold{QUESTION \: 4}$

CUBE OF 3375

$\sqrt[3]{3375}$

$\sqrt[3]{15 \times 15 \times 15}$

$\huge \boxed{15}$

$\bold{QUESTION \: 5}$

Evaluate 97 × 103 by an identity.

97 = (100 -3)

103 = (100+3)

So,

= (100+3)(100-3)

$= {100}^{2} - {3}^{2}$

= 10000 - 9

$\huge \boxed{9991}$

$\bold{QUESTION \: 6}$

A die is thrown so,

TOTAL CONDITION = 6 {1,2,3,4,5,6}

POSSIBLE CONDITION = 3 {2,4,6}

$\boxed{PROBABLITY = \dfrac{POSSIBLE \: CONDITION }{TOTAL \: CONDITION }}$

$PROBABLITY = \dfrac{3 }{6 }$

$\huge \boxed{PROBABLITY = \dfrac{1}{2}}$

$\bold{QUESTION \: 7}$

$\angle SRQ = 105$

$\angle w + 105 = 180$

(Straight line angles)

$\angle w = 180 - 105$

$\boxed{\angle w =75}$

By property of parallelogram sum of consecutive sides of parallelogram is 180 so,

$\angle z + 105 = 180$

$\angle z = 180 - 105$

$\boxed{\angle z =75}$

$\angle z + \angle x = 180$

$75 + \angle x = 180$

$\angle x = 180 - 75$

$\boxed{\angle x =105}$

$\angle x + \angle y= 180$

$\angle 105 + \angle y= 180$

$\angle y = 180 - 105$

$\boxed{\angle y =75}$
