Answer: 4) x° = 33.5°

5) x° = 31°

Step-by-step explanation: 4) It is supplementary i.e. the angle add up to 180° .

(4x+5)° +41° = 180°

4x+46 = 180°

4x = 180-46 = 134

4x = 134/4 = 33.5°

5) It is complementary i.e. angles add up to 90°

x°+(2x-3)° = 90°

3x - 3 = 90

3x = 93

x = 31°

Hey there!

Firstly, you need combine your like terms

$\bold{2.2AND-4}$
$\bold{0.3d}$ stays the SAME
$\bold{2.2-4=-1.8}$
$\bold{0.3d+(-1.8)}$
Combine the negative and the plus and make a negative symbol
$\boxed{\boxed{\bold{Answer:0.3d-1.8}}}$

Good luck on your assignment and enjoy your day!

Which number below best represents a depth of two meters below the ground?

Slav-nsk [51]

Answer:

-2

Step-by-step explanation:

We usually start measuring the height from the ground, so basically the positive direction is above the ground, for example 2 is the best number which represents 2m above the ground.

So the negative sign represents the depth below the ground.
