Firstly we have to find rhe highest common factor which is in this case 3 so firstly we should multiply the brackets by the HCF 3 then add the two numbers divided by 3 so 3(3+7)

Can someone help answer at least one? :) ty

Vika [28.1K]

Answer:

Step-by-step explanation:

a). Ratio of OP and RT = $\frac{OP}{RT}$

= $\frac{12}{3.6}$

= $\frac{10}{3}$

b). Since ΔOPQ ~ ΔRTS, their corresponding sides will be proportional.

$\frac{OQ}{RS}=\frac{OP}{RT}$

$\frac{OQ}{4.5}=\frac{10}{3}$

OQ = $\frac{10\times 4.5}{3}$

OQ = 15 cm

c). m∠P = m∠T = 60°

d). m∠Q = m∠S

By applying angle sum theorem in ΔRST,

m∠R + m∠S + m∠T = 180°

26° + m∠S + 60° = 180°

m∠S = 180° - 86°

= 94°

Therefore, m∠Q = m∠S = 94°

Choose the best decimal equivalent to 5/8

vlada-n [284]

To convert this fraction to a decimal, just divide the numerator (5) by the denominator (8): 5 ÷ 8 = 0.625. So,

5/8 = 0.625
