Okay, first of all, you are probably stuck and don't understand what an exterior angle is. I don't know how to explain it but the exterior angle in this case is ∠DAB.
<h2>∠DAB = ∠ABC + ∠BCA</h2><h2> = 90° + 62°</h2><h2>= 152°</h2><h2 /><h2>They said that the exterior angle was instead 128 degrees. This means that now the sum of the angles of B and C are 152 degrees, or, 152 - 128 = 34 degrees greater.</h2>
To solve, you have to use the Cosine of 41°. This is Adjacent side over Hypotenuse. Plug in the known side length and solve for x
Tan 41° = x / 55
x = Tan 41° · 55
x = 47.81 units
This would make the correct answer C. 47.81.
Hope this helps. Good luck! :)
Answer:
The total cost of the meal is $58.56.
Step-by-step explanation:
The question is asking for problem solving with percentages. In order to multiply by a percentage, we must first convert the percentage to a decimal by diving the percent by 100. Since the Hu family is going to leave a 15% tip on the pre-tax amount of $48, we will need to multiply 48 x .15 = $7.20. The Hu family must also pay a 7% sales tax on the cost of the meal. In order to find the cost of the meal, including tax, we take the price of 48 x 1.07 = $51.36, which would be the original cost plus an additional 7% tax. Lastly, we would need to include the tip to the post-tax total: $51.36 + $7.20 = $58.56.
Answer:
D. -5, -3
Step-by-step explanation:
-10 / 1/2 = -5
-6 / 1/2 = -3
also / means divided
if you wouldn't mind giving me brainliest, i'm just trying to rank up.
Hello :
y = -2x² - 9x+5
the y - intercept when : x=0 so : y =-2(0)²-9(0)+5 = 5
