6 0

Answer:

7) 14✓2

8) 14

are the answers.

Step-by-step explanation:

in a triangle the sum of angles is 180 deg.

the third angle will be = 180 - 90 - 45

= 45 deg

since 2 angles in the triangle are 45 deg it means the triangle is isosceles

and in isosceles triangle the sides opposite to equal angles are equal which means

z = 14 (answer to question 8)

now in right angle triangle, by pythogoras theorem,

hypotenuse ² = base ² + height ²

thus

{w}^{2}  =  {z}^{2}  +  {14}^{2}  \\  {w}^{2}  =  {14}^{2}  +  {14 }^{2}  \\   {w}^{2} = 2 \times  {14}^{2}  \\ w =  \sqrt{2 \times  {14}^{2} }  \\  =  \sqrt{2}  \times 14 \\  = 14 \sqrt{2}

answer to question 7
