Mathematics

Serggg [28]2 years ago

Answer:

See below for an explanation

Step-by-step explanation:

I'm unsure of your answer choices, so I'll show you how to solve for the remainder of the whole triangle:

Since we are given a hypotenuse of 5 and a side length of 4 which is adjacent to ∅, the trig function to solve for ∅ would be cosine because cos∅=adjacent/hypotenuse (SOHCAHTOA). This means cos∅=4/5 and taking the arccos (the inverse of cosine aka. cos^-1) of both sides gets us ∅=36.87°

Side AC can be solved by using the Pythagorean Theorem since a²+b²=c² can be turned into 4²+b²=5². We would then have 16+b²=25 which is also b²=9, thus taking the square root of both sides gives us b=3 (since distance is positive). Thus, side AC has a length of 3 units.

∠A can be found by using the Triangle Angle-Sum Theorem. Since all the interior angles of a triangle must add up to 180°, then ∠A+∠B+∠C=180°. We know that since ∠B=36.87° and ∠C=90°, then we have the equation ∠A+36.87°+90°=180°. Combining like terms on the left side gets us ∠A+126.87°=180° and subtracting on both sides get us ∠A=53.13°

<u>Final sides and angles of the triangle:</u>

∠A=53.13°

∠B=36.87°

∠C=90°

BC=4

BA=5

AC=3

What is the slope and the y-intercept of f(x)= -2x+6
murzikaleks [220]

Answer:

slope = - 2 and y- intercept = 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - 2x + 6 ← is in slope- intercept form

with slope m = - 2 and y- intercept c = 6

Find the sum of 2/9+3/5​
LUCKY_DIMON [66]

Answer:

37/45

Step-by-step explanation:

Find the least common denominator, in this case, it would be 45

2/9 (multiply both the numerator and denominator by 5) = 10/45

3/5 (multiply both the numerator and denominator by 9) = 27/45

10/45 + 27/45 = 37/45
