We have been given that the hypotenuse of a right triangle is equal to 1.2 cm and the interior angles are 60 degrees, 30 degrees, and 90 degrees.
We know that hypotenuse corresponds to 90 degrees angles.
We also know that the hypotenuse is equal to twice the length of the shorter leg and shorter leg is the opposite side to 30 degree angle.
To find the length of shorter leg, we will divide length of hypotenuse by 2.
Therefore, length of shorter leg is 0.6 cm.
We know that the longer leg, which is across from the 60 degree angle, is equal to multiplying the shorter leg by 
.
Therefore, length of longer leg is approximately 01.04 cm.
Answer:
∠ A = 48°
Step-by-step explanation:
Supplementary angles are those angles that measure up to 180 degrees.
∠A and ∠B are supplementary angles. If m ∠ A = ( 4 x − 16 ) ∘ and m ∠ B = ( 8 x + 4 ) ∘,then find the measure of ∠ A
Step 1
∠A + ∠B = 180°
(4x−16)° + (8x+4)° = 180
4x - 16 + 8x + 4 = 180
12x -12 = 180
12x = 180 + 12
12x = 192
x = 192/12
x = 16
Step 2
To find the measure of ∠ A
∠ A = 4x - 16
= 4 × 16 - 16
= 64 - 16
= 48°
Therefore,
∠ A = 48°
Just as you look at it, the only factor common to all three terms is 'x'.
So you can factor the 'x' out and make the equation . . .
x (3x²-19x - 14) = 0
Right there, that tells you that [ x = 0 ] is a solution of the original equation.
But you're not looking for solutions, you're looking for factors, so you continue.
What about that ugly trinomial: [ 3x² - 19x - 14 ] ? Can that be factored ?
Not easily. But if you stuff it into the quadratic equation, you'll find two solutions
to the equation
3x² - 19x - 14 = 0
and you'll recall that (x - a solution) is a factor of the left side.
So you can find the remaining two factors of the original trinomial.
Answer: I have no idea.
Step-by-step explanation:
well what i got was:
the exact form: 233/28
decimal form: 7.96428571...
mixed number form: 7 27/28
not sure if this is right at all but i hope it helps at least a little
