Answer:

Step-by-step explanation:

Three equal sides, so lets find one by solving for x

6x + 16 = 9x-11

-3x = -27

x = 9

6(9) + 16 = 70

9(9) - 11 = 70

70(3) = 210 cm

Find the hcf of 15a²b² and -24ab | plzzz solve

tino4ka555 [31]

Answer:

$\large \boxed{\sf \ \ \ 3\cdot a \cdot b \ \ \ }$

Step-by-step explanation:

Hello,

First of all, let's find the factors of these two numbers and I will put <u>in boxes the common factors.</u>

$15a^2b^2=\boxed{3}\cdot 5\cdot \boxed{a} \cdot a \cdot \boxed{b} \cdot b \\ \\ \\-24ab=(-1)\cdot 2 \cdot \boxed{3} \cdot 4 \cdot \boxed{a} \cdot \boxed{b}$

The Highest Common Factor (HCF) is found by finding all common factors and selecting the largest one. So, in this case, it gives

$\large \boxed{\sf \ \ \ 3\cdot a \cdot b \ \ \ }$

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The three angles of a triangle are in the ratio of 2:3:5. calculate the size of the biggest angle.

Inessa05 [86]

Answer:

80°

Step-by-step explanation:

The sum of the angles of a triangle is always 180°.

∴ 2x + 3x + 5x = 180°

10x = 180°

x = 180 / 10

x = 18

The biggest angle = 5x

= 5 * 18

= 90°
