What's y and x pls I need answer​

1) x = 21deg, y = 146deg

2) x = 52deg, y = 128deg

3) x = 20deg, y=80deg (assuming we're computing angles of the kite, not of the triangles).

4). a = 116deg, c = 64deg

Step-by-step explanation:

Problem 1:

The kite is symmetrical, so y = 146deg.

we can compute x as 360deg - 146deg - 146deg - 47deg; because the sum of angles is 360deg in a quadrangle.

360deg - 146deg - 146deg - 47deg = 21deg

Problem 2:

y = 128deg; as it's symmetrical

x = 180deg - y = 52deg

Problem 3:

The smallest triangle has angles y/2, 50deg and 90deg, so

y/2 = 180deg - 90deg - 50deg = 40deg

y = 80deg (this assumes y is the angle of the kite, not half).

Similarily,

x/2 = 180deg - 80deg - 90deg = 10deg

x = 20deg (again, assuming x is the angle of the kite, not half).

Problem 4:

a = 116deg

c = 180deg - 116deg = 64deg (see problem 2).

step-by-step explanation:

b

step-by-step explanation:

given

- 2 (3x + 12y - 5 - 17x - 16y + 4 )

simplify the parenthesis by collecting like terms

= - 2 (- 14x - 4y - 1) ← distribute the parenthesis by - 2

= 28x + 8y + 2 → b
