Answer:
Step-by-step explanation:
take 45 degree as reference angle
use sin rule
sin 45=opposite/hypotenuse
1/=x/2
do cross multiplication
x= *
x=2
x=2/
x=
pythagoras theorem
a^2+b^2=c^2
( )^2+y^2=(2 )^2
2+y^2=8
y^2=8-2
y=
<u>Answer:</u> The first number is 2, the second number is 3 and the third number is -2
<u>Step-by-step explanation:</u>
Let the first number be 'x', the second number be 'y' and the third number be 'z'
The equations according to the question becomes:
⇒ x + y + z = 3 ....(1)
⇒ x - y + z = -3 ....(2)
⇒ x - z = 1 + y ....(3)
Rearranging equation 3:
⇒ x - y = 1 + z .....(4)
Putting in equation 2:
⇒ 1 + z + z = -3
⇒ 1 + 2z = -3
⇒ z = -2
Putting this value in equation 4 and equation 1, we get:
⇒ x - y = -1
⇒ x + y = 5
Cancelling 'y' by eliminiation method and equation becomes:
⇒ 2x = 4
⇒ x = 2
Putting value of 'x' and 'z' in equation 1:
⇒ 2 + y - 2 = 3
⇒ y = 3
Hence, the first number is 2, the second number is 3 and the third number is -2
Answer:
−5−6
Step-by-step explanation:
Hope this helps c:
Actually to find out the area of the given triangle we don't need to know the measurements of y nor z. Base length x and height h are enough as the formula for triangle's area is 1/2xh.
A = 1/2 * x * h
A = 1/2 * 15 * 6
A = 15 * 3
A = 45
Answer: Area of the given triangle is <u>45 square inches</u> (answer B).
