Find the missing angles

Elina [12.6K]

Answer:

z=116 (opposite angles are equal)

y=180-(116+27)=37(angles in a triangle sum up to 180)

(z) + (27+x) =180(interior angles on same side are supplementary

116 + 27+ x =180

x= 37

How do you simplify (25/a -a l) / (5+a)

andrey2020 [161]

Simplify the following:

(25/a - a l)/(a + 5)

Put each term in 25/a - a l over the common denominator a: 25/a - a l = 25/a - (a^2 l)/a:

(25/a - (a^2 l)/a)/(a + 5)

25/a - (a^2 l)/a = (25 - a^2 l)/a:

Answer: ((25 - a^2 l)/a)/(a + 5)

Help!! ASAP, please! Fill in the missing blanks for the radical equation.

Naily [24]

Answer:

x = 18

Step-by-step explanation:

Given $3 \sqrt[4]{(x-2)^3}-4 = 20$

now adding '4' on both sides, we get

$3 \sqrt[4]{(x-2)^3}-4+4= 20+4$

$3 \sqrt[4]{(x-2)^3} = 24$

i) $3 \sqrt[4]{(x-2)^3}$ = 24

cancelling '3' on both sides, we get

$\sqrt[4]{(x-2)^3} = 8$

ii) $\sqrt[4]{(x-2)^3}$ = 8

iii) $(x-2)^{\frac{3}{4} } = 8$

$(x-2)^{\frac{3}{4} } = 2^{3}$

iv) $(x-2)^\frac{3}{4} )^{\frac{1}{3} } = (2^{3})^\frac{1}{3}$

now simplify on both sides,we get

$(x-2)^\frac{1}{4} = 2$

$((x-2)^{\frac{1}{4} })^4 = 2^4$

simplify we get solution is

v) (x-2) = 16

vi) final answer is x = 16 +2 =18
