Answer:
Does have
Step-by-step explanation:
to understand this
you need to know about:
- Pythagoras theorem
- rectangle
- PEMDAS
given:
- length:45
- width:28
- diagonal:53
tips and formulas:
- Pythagoras theorem:a²+b²=c²
- to figure out whether the frame has perfect right angles or not you have to use Pythagoras theorem since this theorem is only true for right angle triangle and also a rectangle has perfect right angles
let's solve:
[tex]step - 1 : define[/tex]
[tex] \sf {45}^{2} + {28}^{2} = {53}^{2} [/tex]
[tex] \sf \: step - 2 : \sf \: check \: the \: equality[/tex]
- [tex] \sf simplify \: squares : \\ \sf 2025 + 784 = 2809[/tex]
- [tex] \sf add : \\ \sf 2809 = 2809[/tex]
[tex]\text{$\therefore$ the frame does have right angles}[/tex]
