Answer: x=102
Steps:
This is an isosceles triangle which mean 2 angles and 2 sides are congruent. In this case, the 3.3 sides corresponds to the 39 degree angle. This means that the other angle next to x angle is also 39 degrees.
39+39= 78
All the angles in the triangle needs to equal 180.
So subtract 78 from 180 to find the degree of x angle.
180-78= 102

Step-by-step explanation:
Selling price = (100+5)/100 × 1400
= 105 × 14
= $ 1470.00
Answer:
143°
Step-by-step explanation:
R is the second letter of the name QRSTU, so its corresponding angle in the congruent figure is the second letter of DEFGH. That letter is E, so ...
∠R ≅ ∠E = 143°
Let's say that the number of cups of strawberries Jada needs for the whole cake is x. The problem says that 3/4 of the cake is equal to 1 cup of strawberries, so we can set up the following equation:
3/4x = 1
We can solve this equation by multiplying both sides of the equation with 4/3, so it cancels out with the 3/4. Make sure to do this to both sides!
So, you get:
x=4/3
Jada needs 4/3 cups of strawberries for the whole cake.
