Answer:
x = 6
Step-by-step explanation:
These two angles make a complementary angle meaning the sum of the angles will be 90°. We can use this information to make an equation to solve for x.
10x + 30 = 90 (Given)
10x = 60 (Subtract 30 on both sides)
x = 6 (Divide 10 on both sides)
<em><u>Expression that represent the show the total cost for any number of rose bushes and tomato plant is:</u></em>
<em><u>Solution:</u></em>
Let "x" be the number of roses bush
Let "y" be the number of tomato plant
Cost of 1 rose bush = $ 5
Cost of 1 tomato plant = $ 2
To find: Expression that represent the show the total cost for any number of rose bushes and tomato plant
Total cost = number of roses bush x Cost of 1 rose bush + number of tomato plant x Cost of 1 tomato plant
Thus the expression is found where, x and y are the number of rose bush and tomoato plant bought respectively

Answer:
6√2.
Step-by-step explanation:
Triangles CDE and DBE are similar.
Therefore:
a / 18 = 4 / a
a^2 = 4*18
a^2 = 72
a^2 = 36*2
a = √36*√2
a = 6√2.
