Answer:
1) 250°, 2) 44°
Step-by-step explanation:
1) See attached
If we add a line ⊥ to both AB and DE, we can find x as a sum of 2 internal angles of right triangles and 180°
∠D internal = 360°-312°=48°
x=180°+(90°-62°)+(90°-48°)= 180°+28°+42°= 250°
x=250°
2)
∠ADC= ∠ABC= 180°- ∠ADE= 180°- 110°= 70°
∠DBC= ∠ABC- ∠ABD= 70°-26°= 44°
∠DBC= 44°
Answer:
EB=3.3
Step-by-step explanation:
From the diagram, triangle ABC is similar to triangle DBE.
This means that, the corresponding sides are proportional.
It was given that AC=6, DE=4, CB=5.
We want to find EB=x
Since the ratio of corresponding sides are proportional, we have:

We substitute to obtain:
Multiply both sides by 5 to get:

Add $32.50 + $62.80. The answer will be $95.30. Subtract this from$430.52. Her adjusted balance will be $335.22
It is an equation because it has an equal sign. Whereas an expression does not have an equal sign.
Answer:
−x^2 − 8x
Step-by-step explanation:
Lets say y is the missing value
Add -x^2 to both sides.
x^2+8x+y+−x^2=0+−x^2
8x+y=−x^2
Add -8x to both sides.
8x + y + −8x = −x^2 + −8x
y = −x^2 − 8x
So the whole equation would be
x^2 + 8x + −x^2 − 8x = 0
