Find the value of x. the diagram is not to scale.
a. 90.
b. 35.
c. 45.
d. 145.

The value of x is 45°

Option C is correct.

Step-by-step explanation:

Given the figure of pentagon in which measure of interior angles are

∠1=90°, ∠2=148°, ∠3=(3x+10)°, ∠4=x°, ∠5=112°

we have to find the value of x

As the sum of the internal angles in a simple pentagon is 540°.

∴ ∠1+∠2+∠3+∠4+∠5=540°

90°+148°+(3x+10)°+x°+112°=540°

4x+360°=540°

4x=540-360

4x=180

x=45

Hence, the value of x is 45°

Option C is correct.

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
