Step-by-step explanation:

1.How to find the longer leg of a 45 45 90 Triangle?

ans : If you know the length of one of the legs of a 45-45-90 triangle, the other leg has the same length. For this triangle, the other leg has a length of 8*sqrt(2) units. The hypotenuse's length can be found by multiplying the leg's length by sqrt(2).

By the square root property. If b is a real number, and a^2 = b, then a = ___

Vadim26 [7]

Answer

a = √b or -√b

Step by step explanation

The square root property :

If x^2 = c, then x = √c or x = -√c

According to the property, we get

a^2 = b,

a = √b or -√b

Thank you.

A polygon ABCD is inscribed in a circle. Find m angle D A B.

Natali5045456 [20]

Answer: $\Large\boxed{\angle DAB=62^\circ}$

Concept:

Here, we need to know about the idea of a cyclic quadrilateral.

In a cyclic quadrilateral, the sum of either pair of opposite angles is supplementary, which means they add up to 180°.

Please refer to the attachment below for a graphical explanation

Solve:

Given information

∠DAB = 2x + 4

∠ABC = 4y + 4

∠BCD = 4x + 2

∠CDA = 3y + 8

Derived formula from the concept

∠DAB + ∠BCD = 180°

∠ABC + ∠CDA = 180° (Not Important)

Substitute values into the formula that includes ∠DAB

∠DAB + ∠BCD = 180°

(2x + 4) + (4x + 2) = 180

Combine like terms

2x + 4 + 4x + 2 = 180

2x + 4x + 4 + 2 = 180

6x + 6 = 180

Subtract 6 on both sides

6x + 6 - 6 = 180 - 6

6x = 174

Divide 6 on both sides

6x / 6 = 174 / 6

x = 29

Substitute values into the angle expression of ∠DAB

∠DAB = 2x + 4

∠DAB = 2 (29) + 4

∠DAB = 58 + 4

$\Large\boxed{\angle DAB=62^\circ}$

Hope this helps!! :)
