Answer:
23 Cards were given to your brother.
Step-by-step explanation:
12 + 24 = 36
36 - 13 = 23
Answer:
y=(x-1)(x-4) & 100°
Step-by-step explanation:
<u>Graph</u>
1) there are x-intercepts at 1 and 4so you set those equal to x
ex. x=1 x=4
2) then subtract them over to equal 0 and set it equal to y
ex. y=(x-1)(x-4)
<u>Angle</u>
*IMPORTANT* Straight lines are equal to 180°
∠CBD = 80°
1) So you just subtract ∠CBD from 180°
ex. 180° - 80° = 100°
The sine of any acute angle is equal to the cosine of its complement. The cosine of any acute angle is equal to the sine of its complement. of any acute angle equals its cofunction of the angle's complement.
A
C
B
Since m∠A = 22º is given, we know m∠B = 68º since there are 180º in the triangle. Since the measures of these acute angles of a right triangle add to 90º, we know these acute angles are complementary. ∠A is the complement of ∠B, and ∠B is the complement of ∠A.
If we write, m∠B = 90º - m∠A (or m∠A = 90º - m∠B ), and we substitute into the original observation, we have:
