Answer:
Angle CAD is 44 degrees
Angle ACD is 44 degrees
Angle ACB is 136 degrees
Angle ABC is 22 degrees
Explanation:
29. Triangle ADC is an isosceles triangle because it has two equal sides.
If segments AD and DC are congruent, then segment AC is the base and the base angles of an isosceles triangle are equal.
Let x be angle CAD.
Let's go ahead x;
Therefore, measure of angle CAD is 44 degrees.
30. Measure of angle ACD is 44 degrees (Base angles of an isosceles triangle are equal)
31. Let angle ACB be y,
Let's go ahead and find measure of angle ACB;
So measure of angle ACB is 136 degrees.
32. Let angle ABC be z.
Triangle ACB is also an isosceles triangle so the base angles are the same.
Let's go ahead and find z;
So measure of angle ABC is 22 degrees.
3x^2-2x should be the correct answer
Answer:
x = plus or minus √7
Step-by-step explanation:
Solve the equation 7x^2=49, starting out by dividing both sides by 7. This results in x^2 = 7.
We need to solve for (isolate) x. To do this, take the square root of both sides:
x = plus or minus √7
Answer:
1080.
Step-by-step explanation:
0.00025 tonnes = 0.00025 * 1000 = 0.25 kg.
Total number of packets
(3 *90) / 0.25
= 12*90
= 1080.
Answer:
(-∞, ∞)
Step-by-step explanation:
Unless there are restrictions on the domain, the range of any odd-degree polynomial function is "all real numbers."
<h3>Linear function</h3>
The given function is a linear function, degree 1. This is an odd degree, so the range of the function is "all real numbers."
