Answer:
1.93433
Step-by-step explanation:
Since all triangles have an interior angle sum of 180, the second angle is 45. this also means that x and y are equal. Using the pythagorean theorem, we can produce the equation
. dividing both sides by two we get
. when we take the square root of root 14 we get 1.934335

Answer:
4
Step-by-step explanation:
3*10=10+5s
30 = 10 + 5s
30-10 = 5s
or, 20/5= s
or, 4 =s
therefore the value of s is 4.
thank you
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
