Answer:
Hello! answer: d = 40
Step-by-step explanation:
This is a supplementary angle
Meaning it will add up to 180 degrees
So...
90 + 50 = 140
180 - 140 = 40 therefore. d = 40 hope that helps!
Answer:
2.33 = BC
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
tan theta = opp / adj
tan B = AC / BC
tan 25 = AC / 5
Multiply each side by 5
5 tan 25 = BC
2.331538291 = BC
To the nearest hundredth
2.33 = BC
Answer:
angle 1
Step-by-step explanation:
Using the trigonometric mnemonic SOH CAH TOA, we know that cos or cosine is the ratio between the adjacent side and hypotenuse side.
This means that if cos A = 0.48, A is the measure of the angle which it's relative adjacent side divided by the hypotenuse of the triangle will be around 0.48.
Let's try angle 2, cos (angle 2) = adjacent / hypotenuse = 7.8 / 8.9 = 0.876404494382 ≈ 0.87 ≠ 0.48. Since the proportions are not equal, this angle cannot be the one marked as A.
Since angle 3 is a right angle, the adjacent could be either side so it cannot be correct. Thus angle 1 is correct.
Domain is another word for the x value. so, this question just asking us to solve for y when x = 7
first, substitute in x
y = 3(7) -4
and then solve for y
y = 21 - 4
y = 17
so, the range is 17 when the domain is 7
The perimeter of the polygon, which is a trapezoid with the given parameters, is: A. 25 cm.
<h3>What is the Perimeter of a Polygon?</h3>
To find the perimeter of a polygon, sum all the length of the sides of the polygon.
Given the sides of the trapezoid as 8 cm, 5 cm, and two sides of 6 cm each
Perimeter = 8 + 5 + 6 + 6
Perimeter = 25 cm.
