Y=5
Step By Step:
180-75-75
30
4y+10=30
4y=20
y=5
Since this is an isosceles, you know that angle B is congruent to angle C (they’re both 75°).
2 X $1150 + $1049.34 = $3,349.34
Total cost= $3,349.34
Answer: -7
Step-by-step explanation: The sea level is at 0 so 0-7= -7
t = 2 → A true
given I = PRT
to find T , divide both sides by PR
note that R = 6% = 
= 0.06
T = 
= 42/( 350 × 0.06 ) = 2
Answer:
309in²
Step-by-step explanation:
Area of an octagon is expressed as;
A=2(1+√2)a²
a is the side length of the octagon
Given
a = 8
Substitute into the formula
A = 2(1+√2)(8)²
A = 2(1+√2)(64)
Expand
A = 2(64+64√2)
A = 128+128√2
A = 128+128(1.414)
A = 128+181.01
A = 309in²
Hence the area of the octagon is 309in²
