Answer:
It's not quite right to give the direct answer, yet it's brainly, so i'll do my best. All you have to do is line up all of them from least to greatest, then you have to find the middle of all the numbers. the direct middle, like the middle of a number line, with these specific numbers. Hole this helps!
Step-by-step explanation:
The correct answer is <u><em>(2,−1)</em></u>
By Pythagoreans' theorem,
7.5² = l² × b²
56.25 = l² × b²
Since l = b
56.25 ÷ 2
= l²/b²
= 28.125 mm
∴ l = √28.125
= 5.3033 mm
Area of square
= √28.125 × √28.125
= 28.125 mm²
≈ 28.1 mm² (3s.f.)
Answer:
B = 61.0
Step-by-step explanation:
Since this is a right angle, we can use trig functions
sin theta = opp side/ hypotenuse
sin B = 7/8
Take the inverse of each side
sin ^-1 ( sin B) = sin ^ -1 (7/8)
B =61.04497563
To the nearest tenth
B = 61.0
