A+b+c+d=770
a+b=c+d
a-b=49
c-d=211
Find numbers.

Answers

Answer 1

Answer: a+b = c+d
a+b = 770/2 ( a+b+c+d = 770)
a+b = 385
c+d = 385

a+b+a-b = 385+49
2a = 434
a = 434/2
a = 217
a-b=49
217-49= b
b = 168

c+d+c-d = 385+211
2c = 596
c = 596/2
c = 298

c-d = 211
c-211= d
298-211 = d
d = 87

Therefore, a=217, b=168, c=298, d=87

Answer:

Step-by-step explanation:

Secant is hypotenuse / adjacent, while cosine is adjacent / hypotenuse. In fact, secant = 1/cosine.

Here, we know that cos(θ) = 2/19, so sec(θ) = 1/(2/19) = 19/2.

The answer is thus D.

Answer:

Step-by-step explanation:

sec(theta) = 1/cos(theta)

= 1 ÷ 2/19

= 1 × 19/2

= 19/2

The larger leg of a right triangle is 3cm longer than its smaller leg. The hypotenuse is 6cm longer than the smaller leg. how many centimeters long is the smaller leg please explain how you got it

Answers

$b=a+3\n c=a+6\n a^2+b^2=c^2\n\n a^2+(a+3)^2=(a+6)^2\n a^2+a^2+6a+9=a^2+12a+36\n a^2-6a-27=0\n a^2-9a+3a-27=0\n a(a-9)+3(a-9)=0\n (a+3)(a-9)=0\n a=-3 \vee a=9\n$

The length can't be negative, so the answer is 9 cm.

Let the smaller leg be x.

Thus, larger leg = 3 +x
Thus, hypotenuse = 6 + x

Applying pythagoras theorum ;

$(6+x)^2 = x^2 + (3+x)^2 \n \n or, 6^2 + 12x + x^2 = 3^2 + 6x + x^2 \n \n i.e., 36 + 12x = 9 + 6x \n \n =>6x = 45 \n \n => x = 9$

Thus, the length of smaller peg is 9 cm.

The equation sin (40)= b/20 can be used to determine the length of line segment AC. What is the length of AC? Round to the nearest tenth.

Answers

Provided that the triangle looks like this:

A| \ | \ | \ | \ | \ b| \ 20 | \ | \ | \ | \ |_______40\C a B

Then using the the equation to solve for line segment AC (or b on the diagram):

sin(40) = b/20

b = 20 * sin 40
b = segment AC = 12.9 units

If A is to the left of B on a number line, which of the following must be true?A.) A<B
B.) A=B
C.) A>B

Answers

Answer:

A. $A<B$

Step-by-step explanation:

We have been given that A is one the left of B on a number line. We are asked to choose the correct option from our given choices about the given condition.

We know that the value of numbers on number line increases from left to right.

Since A is on the left of B on number line, therefore, the value of a must be less than B and option A is the correct choice.

A.) A <B I hope i could help you.
