Answer:
m∠B = 107°
Step-by-step explanation:
The given geometric figure is a deltoid or quadrilateral with two pairs of equal adjacent sides whose diagonals are perpendicular.
The longer diagonal divides two opposite angles into two equal parts, which means:
m∠A = 2 · 32 = 64°
m∠C = 2 · 41 = 82
Also the angles m∠B ≅ m∠D = x
The total sum of the inner angles in the quadrilateral is 360°, which means:
2 · x = 360 - ( 64 + 82) = 360 - 146 = 214 => x = 214/2 = 107°
m∠B = 107°

Answer:
7xy^2 - 2xy^2
Step-by-step explanation:
Subtracting 3xy² from 8xy² is 8xy² - 3xy² = 5xy²
And 7xy^2 - 2xy^2= 5xy²
The simplest way to find percent is to take the partial number, divide by the whole number, and multiply the answer by 100%.
= 0.4
0.4 x 100% = 40%.
Answer:
15 miles per hour.
Step-by-step explanation:
105/7=15
44. You can come to this answer by using algebra,
1/2x = 22
Multiply both sides by 2(denominator) thus,
X = 44.
Or you can use lateral thinking and realise that if 22 is 50%, you need to multiply by 2 to reach 100%.
