Answer:
1. AC is perpendicular to BD
1. Given
2. ACB is a right angle
2. Definition of perpendicular lines
3. Triangle ACB is a right triangle
3. Definition of right triangles
4. Angles 1 and 3 are complementary
4. Interior angles of a triangle add up to 180 degrees (Triangle Interior Angle Sum Theorem), and m<ACB = 90 degrees (definition of right angles), so m<1 + m<3 = 90 degrees (subtraction property of equality). By the definition of complementary angles, angles 1 and 3 are complementary.
The answer is 3.
$6 x 6 = 36
45 - 36 = 9
9 divided by 3 = 3 burgers
Answer:
B
Step-by-step explanation:
pls mark brainliest
The answer is b.) 120 degrees
although you come up with 50 you have to pay attention to the significant figures and realize that the seconds only have 1 figure so the answer then becomes 5.
