Answer:
b. about 63.9 units and 41.0 units
Step-by-step explanation:
In question ∠a= 29° and Side of a= 15 and b= 20
Using sine rule of congruence of triangle.
⇒
⇒
Using value of sin 29°
⇒
Cross multiplying both side.
⇒ Sin B=
∴ B= 41°
Now, we have the degree for ∠B= 41°.
Next, lets find the ∠C
∵ we know the sum total of angle of triangle is 180°
∴∠A+∠B+∠C= 180°
⇒
subtracting both side by 70°
∴∠C= 110°
Now, again using the sine rule to find the side of c.
⇒
Using the value of sine and cross multiplying both side.
⇒ C=
∴ Side C= 28.92.
Now, finding perimeter of angle of triangle
Perimeter of triangle= a+b+c
Perimeter of triangle=
∴ Perimeter of triangle= 63.9 units
Answer:

Step-by-step explanation:
- Substitute in values
Answer:
Therefore, the price would be 1.76 per pound of the walnut.
Step-by-step explanation:
To calculate the price per pound of the walnut, we just have to divide that price that Ava paid for the given amount of walnuts. We calculate as follows:
Price per pound = 4.40 / 2.50 pounds of walnuts
Price per found = 1.76 / pound of walnut

Answer: He gets $86.71 per square foot
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
<em>Area = 4,875 square feet
</em>
<em>Price = $445,000
</em>
First, we have to divide the price of the house by the area, to obtain the price per square foot:
Mathematically speaking:
$445,000 / 4,875 square feet = $91.2 per square foot (original price)
Now we have to multiply it by the offer in decimal form (95/100 =0.95)
$91.2 x 0.95 = 86.71 per square foot
He gets $86.71 per square foot.
