Angles x and 64 deg are "complementary," so x+64=90, and x= 26 deg.
The answer I believe is 3.5
26 x 72 = 1872
40 + 420 + 12 = 472
1872 - 472 = 1400 (the answer)
Answer:
B
Step-by-step explanation:
Ireland is the island on the left, so the north is on the top of Ireland.
The angles of the triangle are given as to have measures of <span>45°-45°-90°. This entails that the triangle is an isosceles triangle where the 2 legs of the triangle are of equal length. We calculate as follows:
c</span>² = a² + b²
c² = 2a²
4² = 2a²
a = 2√2
Hope this answers the question. Have a nice day.
