Answer:
153 ? im not sure srry if wrong
Step-by-step explanation:
20 + 7 = 27
180- 27 = 153
Given,
(b) Base = 7mm
(h) hypothesis = 20mm
(p) Perpendicular = ?
We know,
[tex]p^{2} = {h}^{2} - {b}^{2} \\ [/tex]
p^{2} = {20}^{2} - {7}^{2}
p^{2} = 400 - 49
p^{2} = 351
[tex]p = \sqrt{351} [/tex]
[tex]p = 3\sqrt{39} [/tex]
