TQRS is an inscribed quadrilateral.
5 x - 52° + 3 x + 40° = 180°
8 x - 12° = 180°
8 x = 180° + 12°
8 x = 192°
x = 192° : 8 = 24°
m∠ R = 3 · 24° + 40° = 112°
m∠ T = 5 · 24° - 52° = 68°
m∠ S = 360° - ( 68° + 68° + 112° ) = 112°
Answer:
m∠R, m∠S, m∠T = <span>112°, 112°, 68°.</span>
5/5=1, 1/2=0.5, After you divide the fractions you then only have to divide the numbers. 1/0.5=2
Answer:
Step-by-step explanation:
A^2 + b^2 = c^2
324 + 6400 = c^2
6,724 = c^2
c = 82
82 cm.
Answer:
11) x = 11
12) x = 11
Step-by-step explanation:
11) Δ RQP and Δ RLK are similar.
Hence, the ratios of the corresponding sides of the two triangles will be constant.
So, 
⇒ 
⇒ 
⇒ x - 4 = 7
⇒ x = 11 (Answer)
12) Δ QRS and Δ QDC are similar.
So, 
⇒ 
⇒ 2x - 14 = 8
⇒ 2x = 22
⇒ x = 11 (Answer)
