Answer:

Step-by-step explanation:

The square root of 88 is between two perfect squares.

Remember 9*9 = 81 and 10*10 = 100. Since 88 is between 81 and 100 then its square root is between them as well.

√81 < √88 < √100

They simplify as perfect squares to: 9 < √88 < 10

Consecutive angles in a parallelogram are supplementary. What is the value of x?

Naddika [18.5K]

Step-by-step explanation:

HERE,

$\angle{PQR=20+2x }$ ⠀

$\angle{ QRS=6x }$ ⠀

we know that,

sum of consecutive angle of a parallelogram =180

so,

According to the question,

$\angle{PQR}+\angle{QRS}=180$ ⠀

$\tt{20+2x+6x=180 }$ ⠀

$\tt{8x+20=180 }$ ⠀

$\tt{8x=180-20 }$ ⠀

$\tt{8x=160 }$ ⠀

$\tt{x=\dfrac{160}{20} }$ ⠀

$\tt{ x=20 }$ ⠀

Given the figure above, determine

tensa zangetsu [6.8K]

Answer: Angle 2 = 47 degree

Explanation:

Proof that triangle ACB ~ triangle CBD

Angle ABC = Angle CBD (same angle)

If one pair of the angle is the same then the other pair should also be equal because both the triangle are Isosceles.

=> angle ACD = Angle CDB

Therefore, triangle ACB ~ triangle CBD (AA)

=> angle C = Angle A

But angle A = 47 degree

Therefore, Angle C = Angle 2 = 47 degree
