Does sin cos tan only work with right triangles

1 answer:

Yanka [14]2 years ago

Trigonometric functions aren't to do with triangles specifically, they are to do with angles.

So no, they aren't only for right angled triangles.

For example, the formula (1/2)ab * sin(c) calculates the area of a triangle, and will work on isosceles and scalene triangles.

QUESTION 1 Evaluate −30 ÷ −6. a 5 b −5 c 6 d −6 QUESTION 2 Evaluate 62 ÷ (3 + 9). a3 b4 c12 d21 QUESTION 3 Danny made a mistake

Mashcka [7]

Answer:

A; ?; Line 3

Step-by-step explanation:

Question 1:

-30 divided by -6 is 5.

The negatives cancel each other out.

And 30 divided by 6 is simply 5.

Question 2:

$62\div(3+9)$

Do the operation inside the parenthesis first:

$62\div12$

Divide. 12 does not go into 62 evenly. 12 times 5 is 60, so the answer is 5 remainder 2:

$62\div12=5\text { R}2$

Or in fractions:

$31/6$

(Was there a typo? From what you've given me, the correct answer is not listed.)

Question 3:

So we have to following steps:

$\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+11(2)\\\text{Line 4: }21+22\\\text{Line 5: }43$

The mistake is in Line 3. Danny cannot just combine 5+6(2) into 11(2). Instead, he should multiply 6(2) and then add. Thus, the correct solution is:

$\text{Line 1: } 21+35\div7+6(2)\\\text{Line 2: }21+5+6(2)\\\text{Line 3: }21+5+12\\\text{Line 4: }26+12\\\text{Line 5: }38$

What is the slope, y-intercept and x-intercept of 2x + 4y = 8

QveST [7]

2x+4(0)=8
2x=8
x intercept; (4,0)
2(0)+4y=8
4y=8
y intercept; (0,2)
2x+4y=8
4y=-2x+8
4y/4=-2/4+8/4
y=-1/2x+2
