First, split the triangle into half.
So the angle 38 becomes 38/2=19.
So we know two angles in the triangle:
One is 19 degrees.
The other one is 90 degrees (marked red).
The angles in a right-angled triangle add up to 180 degrees.
So to find the x angle, we calculate it by:
180 - (90+19) = 71
(the sum of three angles) - (the sum of the two known angles) = unknown angle
So x = 71 degrees.
Answer:
g= 4 and g =5
Step-by-step explanation:
12/16,
6/8,
3/4, and
45/60
are all equivalent to 24/32.
Now that I've listed those four, there are
only an infinite number of others remaining.
Answer:
x∉R
Step-by-step explanation:
1) Solve the quadratic equation 9x²-18x+14=0 using x=(-b±√b²-4ac)/2a:
x=(-(-18)±√(-18)²-4×9×14)/2×9
2) Evaluate the power, calculate the product and multiply the numbers:
x=(18±√324-504)/18
3) Calculate the difference:
x=(18±√-180)/18
4) The square root of a negative number does not exist in the set of Real Numbers:
x∉R
Answer:
D
Step-by-step explanation:
![( {2 x})^{ \frac{1}{3} } - 7 = \sqrt[3]{2x} - 7](https://tex.z-dn.net/?f=%28%20%7B2%20x%7D%29%5E%7B%20%5Cfrac%7B1%7D%7B3%7D%20%7D%20%20-%207%20%3D%20%20%5Csqrt%5B3%5D%7B2x%7D%20%20-%207)
