Answer:
i think it's A.) 5.5
Step-by-step explanation:
A right triangle has 90°
Given: 15 and 20
15 + 20 = 35
90 - 35 = 55
55 is the missing angle
Round to the nearest tenth: 55 ÷ 10 = 5.5
(3a^4 – 2a^2 + 5a – 10) – (2a^4 + 4a^2 + 5a – 2)
= 3a^4 – 2a^2 + 5a – 10 – 2a^4 - 4a^2 - 5a + 2
= a^4 - 6a^2 - 8
The answer is £25.85
£47
55% = 23.5
5% = 2.35
55% = 23.5+2.35=£25.85
