Answer:
CB = 5, 
Step-by-step explanation:
Assuming that the marks next to angle D mean that 
, then there is enough information to conclude that the two right triangles are congruent (HA theorem--hypotenuse/angle).
Then all the corresponding parts of the two triangles are congruent, including segments BA and BC, making them the same length.
4x + 1 = 9x - 4
Solving for x,
1 = 5x - 4
5 = 5x
1 = x
Pluggint x = 1 into the two expressions reveals that the length of segment CB is 5.
The two small angles at D are congruent, so 
.
Answer:
infiintie\
Step-by-step explanation:
//I take it you're trying to find the area or circumference of a circle, so I'll do both.
= area
3.14 * <span>
= 28.26 (2 d.p)
</span>2
r = circumfrence
<span>2 * 3.14 * 3 = 18.84 (2 d.p)</span>
Answer:
A. 160
B. 960
Step-by-step explanation:
The interest earned after 5 years is the balance - the initial balance: 160
The balance is 800 * (1 + .04*5): 960
Pizza = x
Sandwiches = 2(x-4)
So if sandwiches = 62
62= 2(x-4), multiply 2 into the para-thesis
62 = 2x - 8 (add 8 to both sides)
70 = 2x (divide both sides by 2)
x = 35 I hope this helps
