Let's apply the law of sine to calculate angle C
sin(81)/26 = sin(C)/28
0.1646 = sin(C)/28 and sin(C) =1.063. Sine sin(α) cannot be > than 1, so this triangle is invalid
Answer: 315.3 cm / 3.153 meters
Step-by-step explanation:
3,4 meters = 340 cm
340 cm - 24.7 cm = 315.3 cm
Answer:
Each one has 3 even and 3 odd numbers.
For the first one to be even there is a 3/6 probability, which reduces to 1/2.
The probability of the second one being even is also 1/2.
The probability of both being even would be 1/2 x 1/2 = 1/4 probability
Answer:
Step-by-step explanation:
A trapezoid is generally defined as a quadrilateral with <em>exactly one</em> pair of parallel sides. That means a rhombus is not a trapezoid. (No)
A parallelogram has two pairs of parallel sides. (No)
A rectangle may not have equal-length sides, so a rectangle may not be a rhombus. (No)
A rectangle has two pairs of parallel sides, so a rectangle is always a parallelogram. (Yes)
